I came across this buildup in the back of "How to build big-inch chevy small blocks". Alsmost sounds too good to be true!!

383ci: 4.030 x 3.75

506ft-lb @ 4900 RPM (1.32 ft-lb/ci)

I think Ive found me a motor

You do know how much that will end up costing, right?

money=time, ive got plenty of time. i aint in any rush

Stekman

Then go for it. Heads are weak compared to what they could have used.

im wonderin though if the block itself really makes a difference, compared to stock. both iron. what cha think? thats pretty much what I got to start with, and ive already got money into the machine work on it.

Stekman

It's not the material, it's how it's made. A factory block is "lazy." It's designed to be produced en masse. The aftermarket block has much better tolerances, better design, more carefully designed, it's just a better block. Better for any real performance engine. Though, it isn't 100% needed.

REALPOWER

about 8k for mine minus dart block and CNC heads, so add another 2 grand to it. Your lookin at almost 10k into a motor.




here it is,

I now thinkin about swapping the cam that I had originally thought off. from the xe268h to the xe274h. The one the got in the mag im lookin at has a longer duration and more lift, so maybe the xe274 wud be good enuf for me.

Stekman

I thought you wanted the above?

well, im was just usin that as a baseline. Man, im still debating on how I wanna build this motor. budget 383 to get the damn RS rollin, or spendin the proper time and money and buildin a stout motor for a car that I paid $500 for

But either way, its gonna cost me. I put some numbers together and came up with about $3800 not including ignition, exhaust, carb, rockers, heads, intake and misc crap. But, that is with a retro T56 as well.

The Dart Pro 1 CNC 215 cc heads are awesome heads, they flow nearly 300cfm at .600" But more importantly, these heads crank out some impressive flow numbers at 0.300- and 0.400-inch lift.

don't be confused. that's the way all hotrodders get started, buy a cheap car then mod the hell out of it.

i'd be interested to see you get away with the above motor for $3800. more interesting, though, i think, would be where you are going to cut corners to save money. can you elaborate?

well, the figures i put 2gether was before i saw the buildup. My costs incluce the cheap-o powerhouse stroker kit with cr3 rods and 1 piece crank, cam, AFPR, cam kit with lifters, button and bolts, CF DF clutchkit, retroT56 trans and aluminum flywheel. The rest Im still verrrry undecided on, which is why I was thinkin about this build up. This seems to be s very nice set up.

As far as cutting corners, i might go by the mag's set up and then just with some-what cheapers parts (ie. dart block).

what heads are better???

dont cut corners.do everything right the first time or u will be pulling the motor after cheap stuff breaks.Take as long as u want dont rush.

i dont trust magazines.They will make anything sound good.So if i were u id go for the opinion from a few not one performance shops/machine shop ,about your combo.

By the time you're done with all the shortcuts you'll be building the same combo that's been posted here by so many guys that it's etched on my screen.
You could have done a search, and saved yourself the trouble of having to read that article, and then having to figure out how to make it affordable.

SSC

You know if I had that kind of cash to spend on an engine I'd just buy an already built, broken in and dyno'd SB 454. But thats just me.

guys guys, im stil undecided as to what EXACTLY I want to do with the motor part. Its more than likely gonna be a budget 383 like everyone else on here, but in my case thats right up my ally since this is the first motor Ive rebuilt by myself. and rebuildin a 350 IMHO just aint worth it, 383 is the way im goin
