I have a '91 Z28 with a .40 over L98, Trickflow G2 heads, 1.5 roller rockers, Stealthram, 24 lbs. injectors, and a PCM for less chip. I have 2.73's now but plan on 3.73's as soon as the motor is back together. Converter is stock 700R4. I imagine compression would be around 9.5-10 with the 67cc chambers. Trick flow recommends nothing over 236 @ .50, .490", and a 110 LSA because of piston to valve clearance with the turned chambers. I have been waiting for a cam recommendation from Comp since saturday. So I was wondering if anyone has any suggestions. I was think of using a Comp 264, 210 intake at .50, .220 exhaust, .480 on both sides and 112 LSA. Any ideas?

i had very good luck with it in my TPI cars, we also used the old SLP 495/510 with the G2 heads

 

any cam that promises a smooth idle and good vacuum should work for fuel injection with minimum tuning. a roller is the way to go.

 

go to comp's website and download camquest for free. enter all your specs and it will give you like ten or so recommended cams. even if you dont go with a comp cam, it gives the numbers for each cam so you can choose one somewhere else and know what LSA, duration and such that you want.

 

I like this LPE cam:

You wouldn't have to change your rear gear with this one.

 

I suggest searching the boards for existing engine combo's that are similar to yours, like, for example, mine.
