hows this 383 look?
Ok here is what I've come up with.
world products 350 block with splayed mains
stroker forged internals
hyd roller cam 226/230 112 lsa
1.5 rr
edelbrock victor jr heads 64cc
hsr intake
32lb hour injectors
Thanks to all for all the help so far.

It looks economically unbalanced....
Too much money in the block casting (WAY overkill, comparing $$$$ to need)
Not enough cam duration
Not enough rocker, or not enough cam lift
Too much head for the intake system. Compare the cross-sectional area at the top of the intake runner, i.e. the limiting "choke" point of the system, to the head port.... I think you'll see that you will in effect be building 8 large plenums behind 8 little orifices.
Other than that, looks great. I wish I was the one selling you parts.

well I already have the block. Got it for a pretty good deal actually and saves me all the maching costs of an old block.
What are your suggestions for change then?

More cam.... 5-10 degrees more duration; make sure the lift is as much as you can get, after accounting for the rockers, up to the point where whatever heads you get stop flowing more
What's your head budget?
What CID is this motor going to be?

I take it that the world products block you got is already machined for the 383 clearances? if not you will still need to have it machined... otherwise looks like you are going in the right direction and sounds like a good build.

According to the specs on the world products page all their blocks are clearenced for stroker engines. The only thing that seems to need machining is the bore which comes from the factory at 3.990. Really hope I can have this all together by mid june...
