I've read a couple or three different posts on 390 rebuilds here and have gotten very much info but still have a couple of questions.

My 390 is very stock and I'd like to give it some zip. I was thinking 350 to 400 hp, but not sure if this is realistic or attainable. The whole car is stock and I'd like to keep it as stock apprearing as possible, the keyword- appearing.

I think I have the bottom end figured right, correct me if I'm wrong, but stock crank and stock rods, as long as they are not severly damaged, should be good. I shouldn't need to buy a Scat crank or Eagle rods. I would like to use forged pistons.

The heads that are currently on my car are C3AE-C, which I believe are the low cc ones. I would certainly like to use these, but what all should I have done? 2.09/1.66 valves? Roller rockers or adjustable?

I have no idea what cam to use. I don't know if the Edelbrock cam (.460/.480) is too small or the Comp/Crane cams are too big. How do I decide this?

MSD ignition, I figure, is a must.

750 Holley carb, must.

Are the cast shorty headers at a disadvantage over the Tri Y headers, and if so, how much? I'd like to use the cast iron.

Have I missed anything?

Thanks for your help. I appreciate it.
