Ok guys, no flames please. I need some info. on porting and polishing an intake. I have searched on this subject in the past with little or no real info on this subject. Now this is a performer tbi manifold, but I thought that you guys might have some good input due to the fact that tbi and carbs use basically the same type intake. So who can give me some good info or direct me tosome on doing this. Also is there much gain from these mods? I need to use this intake because of ease of install and emissions.

Any help would be great.

Thanks, Mike
