Easy...A good home port and polish job to the heads and then a cam in the 230 degrees of duration area with a 110 degrees of overlap should give it some real guts. Then top off the engine with a RPM manifold or the likes and with low gears (you'll need them), then you can go new Z-28 hunting! Oh, I almost forgot, the first thing on your list (especially with factory heads) is to get David Vizards book, How to Hotrod Small Block Chevys on a Budget. Good luck

vortec heads , a speed pro 224 duration cam .450 / .460 cam , and speed pro flattop pistons. The 2.02 / 1.60 wont help if your cam is to small.

your definately in the 300 range -Will

70nova,have someone DD2000 it for you.
I have a similar set up but with 1.94s and a EX262 cam and mine was DD2000'ed once at 315hp/365Tq and again at 325Hp/366Tq Always figure on about 10Hp less than these dyno programs say though.
With that vette cam from your other post I'd guess about 280-300hp
