For TPI you want a cam for idle to 5,000 rpm. Ported or aftermarket TPI idle to 5500. Really, no more than that you'll be wasting cam and sacrificing power.

A lot of guys are running the LT4 hotcam with greta results in the stock TPI situations. If it was a modded TPI I would say a 224/230 or so COMP XE cam. I would probably run a 218/224 XE cam.

I believe the TPIS ZZX cam is the biggest made that will work with the computerized TPI. You will have to contact them to confirm it, but I'm pretty sure that is right.
