It should make that figure without any issues, however, you will have issues with the stock hood closing. I think the 200cc runners are a bit large for a mild 350, so it maybe a little soggy on the bottom end.

Ditto, I would opt for a 180 runner or a vortec style head.

I have a CC XE274 hydraulic flat tappet cam in my 383 'Vette. I believe the cam may be a little much for a +/- 350. Why not go to a 383 while your doing all the other stuff?

The 280 should work just fine with the increased CI.

You are going to buy new rods and pistons, why not stroke it? Eagle steel cranks are not a lot of money.

I have seen a lot of bad reports on various forums, on the KB Hyper pistons.

I'm running Speed Pro Hyper on my 383.
