383 stroker and cam clearance
I am getting the 41755BIE SCAT stroker balanced assembly. Does anyone know if a cc306 will fit on a regular base circle.. Rotating assembly comes with their ProComp forged I Beam rods..which are suposed to be profiled for strokers. And also how good are the stock exhaust manifolds? Are headers really needed..thanks.

I have done alot of 383's and you can use a off the shelf cam no major problems with cam to rod intereferance. Worst case on a non stroker design, you might have to touch up the rods slightly (light clearancing). I have done 383's with stock rods and it is a matter of slightly rounding off the shoulder of the rod bolts to clear. I have done 383's with 7/16 Scat rods, and they required more clearancing than alot of the others out there, but it still wasn't a real big deal. You aren't taking hardly anything off to make them clear, so rod strength is not affected.

I would also set the oil pan on without a gasket and turn it over. It's pretty common to have to ding the pan so it also clears. Then with the thickness of the gasket, you will have good clearance.

I just used a set of those Scat I Beam rods in a 3.75 stroke LT1 a few months ago.
Had to grind on the bottom of the cyls/pan rail a little.
No interference problem with the stock pan.
No cam to rod interference problems with the cam which was 1.140 Base Circle and .361 lobe.
You definatly should run long headers on a 383 with a cc306.
