CHEAP DIY TURBO BUICK 455-MORE BOOST!

[@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.

Man! That engine sounded SO comfortable after the head gasket change. 2nd run, I was like, "Yep. There's 500 right there." Because it blew on the run with 8-something PSI. And when you rebuilt it, it SHOULD have been even better (which it was). So once you said 9+ PSI, I was like, "That's a wrap, folks." I can't wait to see how this thing performs through all the mods. And that torque... just wow.

You can buy anything from a crankshaft to a custom intake manifold. The fastest fwd lada in drag racing currently has ET 8.1 -301km / h (rotary engine), the fastest lada on a factory engine has ET 9.3s. and so everything is like everyone else, k20-24, c20xe, 2jzgte, sr20 and much more. and we have no trabants)

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.

[@remybrouwer8700]

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.

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.

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.

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.

I think kaiser jeep used Buick 350s for a short time before they were bought by American Motors

I built a low compression regular burning 455 for my old '81 Suburban. Worked great towing a car trailer & race car and got better MPG than the SBC it replaced. I estimate it would have turned about 90MPH in the 1/4 which is not bad for a 3 ton regular burner.

If I am not mistaken, GMC truck used Buick engines during the mid 50's to mid 60's. They were lighter and had more torque then the Chevys.

Someone already mentioned go to TA Performance. The 455 was one of the best big blocks GM ever made. Yes, the Buick. Not the Pontiac or the Olds. The timing cover is made of aluminum and usually welds itself to the block. You had better buy one before installing a camshaft. Ask me how I know...
