I'm always fascinated by the inconsistencies on this board. When I first suggested doing a 396, several people said I was crazy because you could get just as much HP out of a 383 and it would be cheaper.
Now, I can go larger, and people are saying I'm crazy because I don't go even bigger, even though it would cost me a LOT more to do so.
Anyway there is certainly some logic in what your saying. And I still haven't made a final decision, except that I will not be doing a 454.

 

Hey it's your block and build, do what you want with it. If I had the dough I would have bought it. Probably would have done as your doing too. Start out with one combo of parts, since you have some already, and maybe start collecting big gun parts for for future cubes and HP improvements.
My goal would be about 600rwhp and a dual stage nitrous set-up for another 300 at the wheels. Now if I can find that damn money tree I'll be all set.

 

Those viewpoints are 100% consistent.

 

what are you doing for heads? I would suggest finding a set of SB 2.2s and getting them converted over.

 

Ignore the naysayers. Go for the 427.

 

I agree, 427 LT1!!!

 

why not 434? hehe

 

I thought a regular LT1 block could be set up to 427?

 

The inconsistencies come from many different walks of life is why. I would never discourage going as big of a stroke you can on the stock block. I did it and couldn't be happier.
However... you have the means to go huge and not taking advantage just seems like it'd be a waste of that block. I was talking about this to a builder and his opinion (you know everyone has one! ) is to go 434 with something like a ported 220cc head and a single plain manifold. A solid roller cam to complement, turn the engine to 8000rpm and you would have huge power. Exhaust would probably be an issue though because I'm not sure if anything larger than a 1 3/4" primary will fit unless going custom. So yeah... lots of $$$.

 

You guys are talking serious money.........


what will this thing run? I have seen several low 9 sec LT1's on a stock block NA. For that kind of money I would want alot more...... a set of custome heads and intake, like a 14* BG or something that flows 400...... Other than that, I don't see any need in it.

I don't like big strok motors, and small tires don't like big stroke......

Funny how everyone talks about these big RPMS with solid rollers.... my solid roller goes 6800 and thats it.....It may go more, but its not making any real big power and just eating up valve springs for 5 h.p. or so.....

 

Perhaps a new set of heads would remedy that situation?
Mine plateus at 7200 and keeps going. The cam is extremely mild compared to other solid roller cams.
Are you saying with the right heads/cam/intake you could not make good power to 8000rpm with big displacement?
Well... if you are going to buy just a block for over 3K that has the ability to make 'BIG POWA" then yeah... big money.

 

there is no need to turn 8k......

a long strok like a 434 will not last long anyway turning 8k...

Plus your not going to be buying little cheap *** behive anymore...its going to have to be checked alot by someone who knows what they are looking at or the whole project could end up scap.




We need to line em up brian, if you win we will go with what you say, If I win we will go with what I say.

 

plus cranks rods, pistons....o.k. now we are into alot of money for a POS, and I could build a mild mark4 motor that will make it look silly....

I am all about bang for the buck, then again.... I am poor. and I build all my stuff in the back yard too....you guys are alot more advanced than me, more knowledge,money, and oppertunities..... So maybe I will just shut up now. I am just talking out of my ***..... thats why you guys have all the fast cars.....

 

You are all salty now.
We will line up, but it won't prove a whole lot of anything since our terds are a night and day difference. Besides that I still need gears/tire that I can't afford right now...
Basically if I were going to do a build like this yeah.. I really wouldn't use behive springs since this isn't some Heinz57 heads/cam build. Surely it would last 8K. Yes it's not necessary to turn that kind of rpm. Not saying it's required, but if built right then higher rpm can yield more power. There's no way you can argue that. Aside from that I'm just trying to live my dream through the OP's with this block and stating what I would do... and you are pooping on my dream. How dare you.
I'll live this dream. You go build your dreamy BB and make my dream look silly.

 

Seems somewhat not smart to me to buy a 3k+ block. Then expect it to be cheap, or expect you to have it all done up quickly. Unless you already have the money. At least he is going 427 now

Buying a 3k block then not useing its potential is like buying a Z28 camaro just to drive it "normal".
