[@douggorton1482]

We have built a dozen 455's and torqued sequenced the same way you do. One of the reasons for going to a single plane manifold on a Buick is to take away some of the low end torque and move it up the power curve a bit. Tires still die.

[@madmod]

I imagine the power handling improves tremendously with less low speed torque. That is a torque shelf, not a curve.

[@302hobronco]

🤣🤣🤣🤣 "tires still die" classic

[@timsharpe3498]

I used to do the same thing when I had a Pontiac GTO. I put a Holley Street Dominator on it just to soften up the low end torque so I could keep it hooked up. Pontiac intakes are so good they don’t really benefit much from a single plane unless you spend a bunch to make it spin 7000 rpm.

Everyone thinks that a diesel makes more torque truth is they just make less horsepower because they don't spin very fast and the only reason they make any torque at all is because of the boost with that same boost level in a gas it would kick their butts all over the place

Due to frame mount differences I just left the big car frame mount on and welded to the chassis (teenagers) I then proceeded to destroy the bias ply L60's on a daily basis. I suppose one of my neighbors must have taken exception to that. Luckily one of my compatriots called me after seeing the aforementioned "stakeout".

That engine is screaming for a Camshaft, that is a lot of volume in those valves, but on the other hand if it was prone to valve instability I guess with heavier valves it will make it even worse but still it will be interesting what that added weight will do with the stock spring, are you going to mill the heads and install .027" Cometic head gaskets to bump up a little further the compression ? if you have the time, please weight the OEM intake manifold vs Aluminum just out curiosity. Definitely torquing cylinder heads from the center out is the right way to do it, I do it in spiral pattern not cross wise, I think both work but for what I have experience with the industrial machines the spiral pattern is what I go for and I have applied to machines that had suffer from matting surface leaks and the spiral pattern had never disappointed, one have to picture in the head how Iron/steel/Aluminum move while torquing with a gasket in between specially one that have a lot of compressibility, and if you want to go more scientific about it install 4-8 dial indicators near each bolts and torque, and watch what happen to the piece of iron/steel/alu with spiral method vs cross method, other factor to take in account if bolt length, and how much they relax after 24hr of being torqued and more so when they heat-up, I torque everything in 3 or more steps depending the amount of torque and after each pass i go thru it again because the first bolts are always loose and it has to do with the gasket compression, with a race engine I will definitely re-torque all bolts after the engine had gone thru some heat cycles and the bolts grain material has relaxed, that I believe will safe you from blown gaskets.

buicks can be great mills and make a lot of power. but the the blocks are cast to save weight. lifter valley is a weak point fot these engines. they make reinforcement plates to keep the lifter bores from collapsing. there are some oiling improvements that people do to race these engines. low rpm's is what this engine was sesigned for. performance was an after thought. pulling a heavy luxury car or station wagon was what they built this engine for. i love your vids and keep them coming.

[@turbo8454]

I've been running a carbureted turbocharged big block Chevy in my one ton pickup since 1986. I built it for towing a trailer up and down the east coast. I've known since I started playing with turbo's in the mid 70's that they are the only answer to the combination power/mileage/drivability/heavy vehicle concerns. While the diesel guys may not like to admit it, cubic inch for cubic inch, manifold pressure being equal, a gasoline engine will out torque and over twice out horsepower a diesel every time. Imagine the new Ford Godzilla V8 with 15 pounds of intercooled boost. The Powerstroke diesel would be way outclassed in torque and horsepower!

There were several experimental variants of the Oldsmobile engines turbocharged from the factory with major big HP results. GM was not a fan of Oldsmobile making more power than the Corvette. So the whole boosted lineup of Oldsmobile powerplants was scrapped. One was the W-43 455 that was rumored to make 1K HP.

If you ever get your hands on one a 350 Buick is a little torque monster as well. An TA had their new aluminum heads for it (first heads ever for the 350). You don't have to go as in depth with that, but itd be cool to see someone do a good walkthrough on one. NO ONE has and its a damn shame they're really stout engines. Plus they love boost. Its basically a bigger 3.8.

[@buickpower455]

The larger flatter valves(augmented with Stage 1 spings) were one of the reasons that Stage 1 engines were rated at a higher compression than standard 455's. Plug the crossover holes with 18mm core plugs. 11/16 is a little too small and barely tighten up without JB Weld or something and 3/4" requires some opening up. The 18mm should fit tight with minimal fuss. Of course if you are maching the heads fitting the 3/4" is no problem. Way back when there actually was an intake gasket with blocked heat crossover available, but that was only for the earlier non-smog heads.

[@Paulster2]

Richard ... before going too far, consider re-ringing and doing a bearing job on this thing, just to give it a fair chance to win. It'd give you a chance to inspect all the bits/pieces to ensure they are up to the task of making power. No sense in destroying the motor over something which could have easily been avoided. You're going to have the heads off again anyway to get them upgraded ... perfect time to refresh the bottom end.

All good shows going into the in's and out's of Buick. Really great that you are evolving the motor as you go. I suspect the dished valves were an attempt to manage heat flow to the stem and seat ...

Big heavy cars pulling camp trailers or ski boats back in the day with the A/C going full blast and never a ping or a rattle - that's Buick :)

@@richardholdener1727 The larger numbers due to increased heat piqued me. Usually I've seen people recommend "ideally" placing the turbo up close to the exhaust valves.

Yes Mike Tomaszewski is the man and knows all about those heads :) just came back to leave a side note.. according to the old men back in the day the 1967 430 heads were THE heads to use for 455s.. the smogger heads have the passages that need filled, and the ports on the 67 heads are notably bigger to the eye. I used to have some but no more. Also the 1970 455 was 10 to 1 compression and the Stage 1 was 10.25 or 10.5 to 1 due to valves.. you might see half a point or better with the flat valves.. thats another reason I used the 430 heads.. smaller chambers.

[@mikealexander4166]

[@timsharpe3498]

I’m not a Buick specialist but I seem to remember that about the Stage 1 heads being the same as stock castings. My old boss built a Stage 1 clone and he just had the machine shop put the 2.14 valves in it. With a Kenne Bell hydraulic cam and headers it ran 12.50 in a 68 Skylark. Stock intake and torque converter, 4.30 gear and 9 inch slicks. That thing had so much torque the license plate Mount would fly open every time it did a dry hop.

[@timsharpe3498]

According to the Buick experts it makes more economic sense to port the heads than to just install the Stage 1 valves because the ports are so restricted that they can barely keep up with a 2 inch valve. Big valves alone are an expensive way to gain about 5 HP.

@@GroovesAndLands yeah i get theres other things at play, but typically if you want torque you look toward more stroke not less. thats why im impressed these put up similar numbers to turbo olds 455s when they are the opposite in terms of bore and stroke.

[@Cuttyman9]

@S Gray yeah, i do think too that to make something work thats big bore short stroke for torque they do have to have a pretty restrictive induction system to offset it (or at least part of it) whereas i dont think thats required as much with a long stroke small bore. im sure there are a ton of tradeoffs but i like that both can put up really big torque numbers. id be curious where they deviate as he puts heads on a buick and we maybe later see a olds 455 against this with the same mods. see if their power curves match because of displacement or if they different because of internal architecture.

[@Cuttyman9]

@S Gray yeah but i think a 455 olds in similar condition should perform about as well. i thought for the condition of everything he has it did pretty well all things considered. i do also like seeing the smog stuff. it honestly makes me realize its a 455, it makes power and i really should just rebuild a 455 olds i have and plop it into my cutlass and enjoy. or the caddy 500 im supposed to receive and strap a turbo to either and see what happens, it seems they like it decently well. i would imagine the revs are limited by the stroke (and weight assiated with having said stroke) so the buicks advantage will definitely be there.

[@Cuttyman9]

@S Gray i definitely agree! i have to pull the engine from the cutlass because my steering rack plans got disrupted by it being setup originally for drag racing so i need to notch the cross member so its got me thinking about all the engines that could go in its place haha. especially if a worn shorblock puts up 750ftlbs lol lol

[@jeremymardlin5381]

Very impressive torque down low in that. Full stage 1 treatment with all the same parts I bet it would make around 700hp at the 9psi mark.

[@MultiScotty12345]

Buick FTW!!! Thanks for the test Richard

[@StevesDIYProjects7]

TY for doing this. was having convo with people while back on facebook about how a boosted 455 could make insane power cheaper over all then other engines. and how after you get y our hp then look at the torque :) love these engines.

[@LucoreAuto]

Depending on what cam you are putting in this thing, it's going to be a WHOLE different monster with a the head/valve upgrades. Carrying that torque number just a little flatter for a little longer will make PILES more power. Looking forward to seeing the results!

[@generouslemon8166]

My guesses for the carb issue is several factors. The intake is a dual plane, the hat has a big effect on the signal to the bowls, and lastly, air bleeds

[@JoshKetchum]

It would be super cool if you could get a TA intake, and an Edelbrock, and a Poston dual plane to show the real difference. Not sure how hard it would be to get ahold of them.. Weiand also made dual quad in take for these things lol

[@mannyr.2756]

Does this mean that everybody's going to scramble and try to find a 455 Buick instead of an LS engine!....

[@mattrodgers4878]

Good Lord, I could only wish! How refreshing it would be to not see a LS swapped into everything.

[@karlsracing8422]

Yes very sick of Ls engines

[@bill2178]

Ive still got so much sbc stuff and I'm much less excited about going to LS now that Richard holdener blew the glass ceiling off by saying every engine does the same thing with the same components

[@joeanderson4819]

I already was looking for a Buick 455 for my ‘67 GS, they’re hard to find around here.

[@raylaux8295]

@@joeanderson4819 Get a Olds instead.

[@eddyagg]

Pretty sure this is the kind of experimental and fun build a lot of us want to see! Your enthusiasm and energy is also contagious haha 👍

[@JoshKetchum]

Buicks love big jets always did. I ran 80 jets square on this same engine with a mild cam intake and headers. Car only ran high 11s with the low compression but TA performance warned me they loved lots of fuel!

[@ryanmalin]

Im loving how thorough you are Rich!

[@kennethpowers8995]

The 455 can actually be a really good performer with the right combination. Head work and a healthy cam especially but a little compression is a help as well. These engines are skipped over a lot but can still win races. Kinda like the Olds 403; a slouch in stock trim but a few breathing mods and you’ve got a powerhouse for cheap.

[@dirtcheapmedia3390]

Haha just put a 403 in my cutlass on my channel feels better than my 350 but the 350 never got the same love yet

[@kennethpowers8995]

@@dirtcheapmedia3390 I’ll have to come check that out. Was your 350 a Rocket motor? Back in 2010-2012 I built a little cruiser out of a 79 T/A with a 403 Olds. Edelbrock heads made the biggest difference I would say, along with a cam that actually had some form of duration to it. The factory cam was so small it made a 350 SBC truck cam seem huge lol.

[@cannonroberts5129]

Thank bud, I’m enjoying the other guys video’s.

[@marcstlaurent3719]

Wow Richard you’re not afraid of work but in my IMOA BG products are junk , Twelve years ago I ran a regular Barry Grant carb on my blow through BBC and was running 99 jets . When the the new blow through came out I bolted that on and it ran 80 jets at 11.0 ratio tuned with my new wide band gauge as engine was in vehicle now and everything seemed fine . When I went to track it melted through number seven piston like a blow torch . What I didn’t notice was behind the metering plate the carb was only partially machined and fuel couldn’t get in that Venturi even though carb had a tag that said it was quality checked and flowed .Too make matters worse it took eight months to get warranty on carb so every reference I see for BG fuel products makes the vein in my head pulse . Replaced with a quick fuel and that ran great till I ran out of fuel at over a 1000 hp as engine kept evolving , now I have a CSU with dual needle and seats using the power valve channels to introduce enough fuel so that I make 1800 hp using only 76 and 80 jets so that it’s a nice street cruiser as well . Kevin at CSU has given me nothing but excellent after sales service this last nine years . At this power level for me on a street strip ( mostly street truck ) this carb works so well and fuel injection would be so expensive that I haven’t wanted to switch .

[@richardholdener1727]

we've run them a lot-and this one just ran on a different motor at 800 hp

[@maxr236]

Totally awesome as usual Richard, I new some guys in high school that had Electra 225s with these in them, what a heavy boat they were! What a sleeper build deuce and a quarter rolls up and you hear that turbo wind up ! Oh crap!

[@williamnottbusch8024]

Sounds like a plan that is going to be fun to watch.

[@davidrutledge6033]

Richard is what you can call a engine whisperer

[@unclesquirrel6951]

This test just makes me think about the ft-lbs that 500 caddy will make under boost 🐿

[@TheRockabillyArts]

I keep checking back a few times a week to see when he's going to do that.
