Engine Pipe Dreams
OK -- here is the thing, I am flat freaking broke. But I just enjoy looking at car stuff online and spend alot of time doing it.
I would like to build a 427BB for my 73 vette. I was wondering what other people have and what kind of power you guys are getting.
I would "LIKE" 600ish HP out of the thing and fit under an L88 style hood, and still be able to use hooker side pipes. I am thinking of making my short block out of a GEN VI block and scat forged crank and connecting rods, whatever forged pistons I can find that give me the compression ratio I want.
Just wondering about your guys thoughts?

Re: Engine Pipe Dreams (Guru_4_hire)
Well I guess tentatively it will be some merlin 320 heads an RPM airgap intake, Demon carb, and a custom solid roller cam.
I may use a single plane on my pipe dreams when I get home and use DD2K.
Would I be able to use the stock fuel lines on my vette going to the gas tank?

Re: Engine Pipe Dreams (Guru_4_hire)
So whats the highest compression you can run a BB on pump gas with? I am fairly sure a SB tops out around 10.5?

Re: Engine Pipe Dreams (Guru_4_hire)
From what I seen 10.5 is about the compression limit, IF everything else is correct, and tightly controlled.....mostly that means DPFI with aluminum heads most carb setups are just not that precise....OR are so rich overall they get poor economy, most mechanical distributors are not all that easy to keep 'right' either....better to let the computer do it....
with iron heads I think 9.5 maybe if very lucky 10 is possible....and that's with high test gas.....if carbed...if DPFI...well good for 1/2 a point anyway....
to run a modern car on today's crap gas and get any decent performance level that is anywhere near consistant enough to be honest....you need DPFI...and of course ignition controll too....closed loop....
ever been to a drag strip and seen how inconsistant most cars are??? years ago before everyone had fuel injection?? very few guys had the time, money, talent to keep a dead nuts on consistant runner....very damn few....
today it's a LOT easier...let the computer do the work....

Re: Engine Pipe Dreams (Guru_4_hire)
Hi Jacob,
Everybody needs pipe dreams :) I have similar "plans" for my '73 Vette, but also not much of a chance of fulfilling them in the near future. Next year I'll probably build a stroker, out of my current SB, to serve me in the interim.
As for the ideal engine, though: if we're going over the top, why build a 427 or 454 BB when these days you can put the same displacement in a small block and save a lot weight? :D

Oh, and here's the link to an earlier article they did about the 427 SB:

Re: Engine Pipe Dreams (FlyingFinn)
Cause I want to build a big block. I figure its a reasonable way to get 550+hp with a flat torque curve.
What makes a Gen V & VI blocks different from previous blocks, and what is a good oil pan for a C3 application. I would like a milodon oil pan with a really good windage tray and stuff.

Re: Engine Pipe Dreams (Guru_4_hire)
If you take a look at the first article link, you'll see that the Bill Mitchell 454 SB makes 600 hp and 575 lb-ft. The dyno table is at http://www.hotrod.com/techarticles/e...54/index1.html
It has the same bore (4.250) and stroke (4.000) as an original 454 BB. So the only real difference is that the block is physically a small-block meaning a pretty big weight savings of 150-200 pounds.
The 427 SB (http://www.theengineshop.com/engine.shtml) is advertised as having 530 hp and 540 lb-ft. peak torque. The torque curve won't be getting any flatter with a "real" BB?
I just don't see why you'd like to haul around the added weight of the big-block, when it won't gain you any power or torque, unless you'd be going for a larger displacement such as 509 or 540 c.i. :confused:
Also, these big small-blocks are a direct bolt-on vs the hassle of installing a big-block in an original small-block car.

Arto

Re: Engine Pipe Dreams (FlyingFinn)
I read the article. Thought about it too. But I want the extra weight, I just think BBs are cool.
Rock on with your project though. Protopline heads flow real well for their money too.
check out the lightening 235s and 242s http://www.protopline.com http://www.flatlanderracing.com/head...ghtalumsb.html
Just some food for thought
I am gonna take the entire car apart and replace all the nuts and bolts, sand blast and paint everything else.
I just think BB are :cool:

Re: Engine Pipe Dreams (Guru_4_hire)
Corey, is the stock fuel line really good for 800 horsepower? I have been contemplating trying to put 1/2 inch line in without removing the body but won't be necessary if they are good to 800. Bill.

Okay. :) I think BBs are cool, too :cool:
My 73 originally came equipped with one, but it's been lost somewhere along the way. So ultimately I'd like to put a 454 back there under the hood, whether BB or SB :steering:
Thanks for the tip about the Pro Topline heads, they do seem to be a very good bang for their buck :cheers:

Re: Engine Pipe Dreams (Intimidator454)
Wonder if a whipple will fit under a L88 style hood. Hmmmmm
Probably need 12 1/2 inches of clearance, doubt I have that
