Well yes and no. The factories that make these engines rely on some knowledge of professional custom engine builders. They use to use alot of "stroker" motors back in the days of the late 70's (1978 in peticular) was when some models had to comply with emissions standards aka the first Catalytic converters. To keep customers happy they would "sneak" another engine in the form of appearances. aka the 350 small block chevy. You can stroke that engine to 454 C.I.D and still use the 350 Valve covers from the factory. All you really had to do was "Deck the Block" and "shave the heads" to give that extra clearance for your valvetrain components and yet you can still use the factory Valve covers. Here's a little fact that goes like this: anything can fit into anything with the right amount of time and alot of money.

 

What does what you said have to do with what I said? btw...you can't stroke/bore a gen1 to 454. Gen3, yes you can.

 

No way can you do that with a gen1 SBC.. Ive built enough of them to know.. the new LS or Gen3 series motors yea you can.. Id say 395 is pushing it for a 350SBC..

 

^^thanks. that dude (not you) needs to learn what he's talking about, and try to not be such a 'know it all'.

 

x2

 

I'm still trying to figure out how "decking the block" and "shaving the heads" generates "extra clearance" for valvetrain.

 

Offtopic a bit, but i watched some of Staceys show Gearz, and its WAY better than the current trucks! show.. I think it was the barstool one..

 

Im pretty sure the guys name was mel but he wasnt blonde. i was only 7 or 8 at the time though so i could be wrong.


GAS is galpin auto sports, Galpin is the largest ford dealer in the country. GAS is just the not cool, not legit, "custom shop" that Galpin has in there original Northridge dealership

 

That west coast customs garbage show sucks, almost as bad as "unique whips". Just a bunch of idiots doing tacky stuff and putting the same 3 piece wheels on everyones car while some short little fat cuban yells the entire time.

 

It does the exact opposite.. Common sense should be used to figure that out.. The only reason you would shave the heads would be, theyre warped or you want to bump up your CR a little bit, and for both of those you only take about .010 of an inch to .025.. Anymore and you mess up the geometry for the manifold to bolt on.. Decking the block is for a higher compression ratio and so that you have a "true" surface, you know its flat, you know your piston isnt still sitting in the hole at all, crap like that..

Hope I helped clarify that false information..

 

I can't tell if you're making a post to everyone or just me since you quoted me. Or if you failed to read my sarcasm and were trying to teach me what I already knew.

But, decking or shaving won't necessarily affect the "geometry for the manifold to bolt on". What it will do however, if enough material is removed, is lift the valve off its seat further throughout the entire lift range. This ends up changing the rocker ratio, needed valve length, or pushrod length etc. It could also lead to having a valve that never seats if enough material is removed. This also brings the face of the valve closer to the piston. Possibly turning a non-interference engine into one, or closing the "cushion" area designed into interference engines.

Again, neither has anything to do with generating clearances for valve train, hence the sarcasm in my post.

 

Oh I caught the sarcasm lol

Im just trying to help clarify that what Nightmare said is wrong

And about the manifold I further thought about what I said and your right it shouldnt be a problem bolting on.. Sorry for the confussion and if you felt I was going after you or something.. I just quoted what you said so that there would be a reference to my post and people werent like whats this guy talking about, since this thread is about a TV show n all haha
