I very interested to see the unput you get on this question. I used scat's 2-ICR6000
(6" forged 4340 i-beam pro stock rod) and I had to grind them to clear the cam. I used Eagle's int. balanced crank for 6" rods. I still had my machine shop balance the rotating assm. Some prefer 6" rods and some 5.7" the same with eagle verses scat.

You need to tell us a lot more about the goals for the engine - approx HP, power adders, rpm limits, etc.
There a "sticky" at the top of the forum topic listing that has a link to a compression ratio calculator. In order to make that calculations, you need specific info regarding your pistons (dish/dome/valve reliefs), your deck height, gasket thickness, etc.
In very general terms, there is very little difference between using 5.7", 5.85" or 6.0" rods. Its all somewhat theoretical, and only becomes an issue if you're designing an engine for the Engine Masters competition.

was going more for street than strip,but yah never know, heads will be ported and polished, might go with a 58 t.b., headers and x pipe,auto was just totally rebuilt with up grades and torq, was thinking i need forged, but i dont have much of a idea on reasonable priced parts, shop told me to leave the cam it has, and for amount of hp +400, the wife is still hooked on are old stang, so its gotta be fast enough to let her mind slip

What is "the cam it has"? If its the stocker, you would be wasting your time doing the 383 build-up, ported heads, high flow exhaust and 58mm TB, and then keeping the stock cam.
Are you looking for 400HP at the flywheel, or at the rear wheels?

I always start a project with a budget as well as as clear a concept as I can formulate about what I am trying to do. Both the concept and the budget may change, but you need them as a starting point.
