how far could I go with a pair of higher flowing heads with a cam, or in better word can I do that withought having issues with the tpi system? the car is a 305 lb9 tpi with an t5 transmission and a maf sensor. my bench mark car to beat is most likely a 05 mustang gt but it would be awesome to give a new wrx a run for its money. first I wanna get the power later I ll work with the traction and the drive train (diff and tranny) when I get more $$$

 

I am thinking about this camshaft for my LB9 TPI build: http://www.summitracing.com/parts/CCA-08-501-8/

As I see you have a 1989 Firebird with a roller block, so you could use this cam for example.

 

ooh cool thanks that answered the other question I had
