Good advice, you need to know how you want to use your car, how much power you want, and how much you want to spend.

I have had very good results with SC’s by using SSI heat exchanges dull outlet, Dansk Sport Muffler w/ dull inlet and 4” outlet, Porting and Polishing heads, Polishing intake runners, Enlarge throttle body, Ignition timing @ 35 degrees @ 6000 RPM then if I have detonation I back off the timing until it is gone.

You already have the better F.I. w/ large intake runners. I would do the bolt on items before tearing your engine down again, to save expense and incase you find the power that you are searching for.

how much does it run a person on an SC motor to port and polish and enlarge the TB?
