Super nice 800-900 hp for my sleeper 86 c10 Silverado :-) Thanks Richard

[@jonathanduke8295]

Very well done Richard straight to the point .

[@shannonsisk]

I’d love to see the newer vortec 8100 with boost, or even on Big Bang !

[@victorparra4227]

A gen 6 454 from a medium duty truck has forged piston and crank, if you get a bigger bore and rise the compression you can get a great engine, CarCraft has an article on this

[@backyardbuilttrucks1]

I would say NO on the forged pistons from gm. Our 02 2500 8.1 had all cast bottom end.

[@asherdie]

@@backyardbuilttrucks1 your 2500 isn't a medium duty.

[@backyardbuilttrucks1]

@@asherdie 1500 , 2500 and 3500 are light duty trucks.

[@asherdie]

@@backyardbuilttrucks1 I know.

[@filitamayo]

@@backyardbuilttrucks1 I thought the 8.1 had forged internals.

[@filitamayo]

Love your videos . Very educational . Thanks for sharing. I wish someone would make marine build videos seems either not many people know how to do it or the ones that do dont like to share the knowledge. Pretty soon there won't be anymore marine mechanics or mechanics that know the difference between marine and auto.

[@genemounce8302]

Gonna need a pair of #1000 springs up front that boat anchor. LOL .. good test Rich!

[@cottoncandy3001]

Gene Mounce it’s not that much heavier

[@diablocustomschoker2058]

the first video that I see straight to the point but what happened next where are the results

[@Brenda915]

512 horse power and 818 hppower whit turbo😊👍💫

[@josephlucckino7090]

Can you do a video generation 6 big block with a turbo but using the stock intake manifold a multi-port intake manifold

[@PetrolHeadMike]

He did

[@ratgasgarage]

Hey Richard, I purchased a bbc with claimed 780 hp, what would it have to have internally bore/stroke/cam is unknown, it has the iron heads, on a tunnel ram 660s carbs, I see roller rockers and stud girdle, im thinking it has to be bored out, thanks for your time

[@adamjohnson5985]

I have a 2000 3500 Chevy with the 454 that I use to tow all my stuff. The upside is that it was inexpensive to purchase and inexpensive to maintain. The downside is not fantastic power and poor mpg. The mpg is not really a concern however more power would be "real nice". How about a real world chassis test with a turbo on a factory truck? I bet there are lots of people out there that would love to see that. After all we have to haul our junk to the track somehow!

[@Compcams1976]

For what you do, the 01-412-8 would be an excellent camshaft! We'd recommend the K01-412-8 for a complete valvetrain refresh.

[@davidvonanderseck8649]

My 454 has a com cams Big Mother Thumper can I add boost? It's got a lot of valve overlap at 107 sep. I'm thinking it will just blow threw

[@javilsx363]

What compression ratio

[@GULFZILLA]

What was the grind number of the cam and did you use copper or stainless head gaskets?

[@musclemasterjr84osking42]

I would like to know as well

[@r.c.r.rproductions8462]

Drinking game: take a shot every time says “big block”

[@Harrybowles1969]

Try saying " I like big blocks" after 10 pints 🤣🤣

[@justinb7534]

i have 496 stroker pro maxx heads quick fuel dominator what should my afr be on 100-200 shot of nitrous and timing

[@davidvonanderseck8649]

Sweet thanks I could use some advice. I’m looking gen 6 454 with zz502 cam and clean up stock heads with springs. Also we want to run boost. With twin gt45s. Will it work. Also I like to go sniper nut money is short. So I’m thinking a turbo carb with MSD to run the coil pacs. Any advice. 800 to 1000 is our hp goal. Any advise.

[@ericperry4934]

Final spark degree

[@Harrybowles1969]

Had different heads on so no stock. Gen 6 heads don't want much timing. Low 30s off boost

[@Bass-100-y3f]

Part numbers especially on the cam I know you said custom grind am work on one at the moment. So call me intrigued

[@Bass-100-y3f]

Lol Didn’t catch the numbers at first so I rewatch it now I can call them up and get that going

[@BronsonOsborne]

check out our videos of a ford FE BOOSTED

[@jasonfikes9514]

How do you determine on how much to open up the piston rings?

[@MississippiDan1]

Theres a formula i can't remember (google ring gap for boost) but .30 with pump gas let us run 475hp nitrous on cast pistons in a BBChevy in two stages. A lot...

[@jasonfikes9514]

@@MississippiDan1 thanks for sharing that.

[@Bob-Sacamano]

You multiply recommended (or tried and tested) clearance for specific usage by cylinder bore diameter. For a high power SBE turbo LS for example I like to go with around 0.0065" top / 0.007" second (give or take depending on expected boost, power output, usage, etc). That much clearance on say a 6.0 LS with a 4" bore gives you 0.026" top ring gap and 0.028" 2nd ring gap. If it's a milder build I'd go with less.

[@filitamayo]

@@Bob-Sacamano so the top one is always a bigger gap.

[@bls454]

not sure if you can call this a junkyard engine when you disassemble it and put 3 or 4 grand worth of parts on it

[@pmd7771969]

These guys never understand you can run gapless rings and not worry about gap. Does he know what a gapless ring is??? Bv

[@johnboy9769]

Man that seems as easy as making ls power lol

[@regal105]

john coffman big block chevys don’t fuck around

[@Harrybowles1969]

Not on that boost straight from the wrecking yard my friend and torque numbers wouldn't be as high.

[@pmd7771969]

Fact, you can get 900 hp from a n a engine. It's been proven 427 hi comp.

[@gamenessfirstinc.2097]

Total cost?

[@Dirtfloorfab]

I'd ballpark 7-9000$ including engine, management, injectors ect

[@battleaxebob45]

Yeesh, I can watch you talk anymore...
