Re: building engine

thatd run alright I guess. find some 388 heads and build a 383 and I think youd be happier.

what?

head size has nothing to do with the CI of the engine

CI is calculated by taking the bore of the engine times the stroke:

bore x bore x stroke x .7854 x 8 will give you the CI of a v8 engine

lets do a 302:

4 x 4 x 3 x .7854 x 8= 301.6 ci

edit* a 383 is a bored engine .030 over, with a 400 crank

4.030 x 4.030 x 3.75 x .7854 x 8= 382.66 ci

you can put 302 heads on it, 327 heads, or 350 heads and its not going to change a thing, other than the compression ratio

Re: building engine

While it sounds neat on paper, I think you would be disappointed. I would guess that a set of over the counter Vortec heads would make at least 20% more horsepower than the very best stock 283 heads you could find.
