I would run the engine for a little while and make sure everything is good with it. I know of two that had problems on startup. Keep the warranty good for a couple thousand miles at least and then the best power adder to that engine is the vortec heads. I put one in my cousins '82 Camaro with stock heads, performer intake, 268 Comp, 600 Edelbrock carb, and Accel HEI distributor. It ran O.K. but when we changed the heads, it was like we built a new engine.
