Got Hi Comp Pistons?

[80fbody]

Got some L2355 .060 over 440 Pistons. Considering switching to hi-comp pistons as it appears the best I can do is about 10-1. Since this is a race only motor would you go with L2295's instead? Looks like it would take the motor from 10-1 to 12-1. Looking for 500-550hp. Have mildly ported 906's. Considering some aftermarket heads.

use the one's you get the most compression from, 2295.

If you are considering aftermarket heads, compare the cc volume of heads to your 906's. I would pick the head you want first, then get the piston to make the CR that you want. If you get the piston first, a new head may have smaller volume & boost CR too high.

you have to watch piston to valve on those domed trw style pistons.they need relifs cut in them for a big cam .....

With fuel prices and cam tec a pump gas engine is my idea with lower compression.Have you looked at Probe?Some of my friends use them in Fords and Chevys run in the 9's and cruise around

I can go 10-1 with my current pistons. This is strictly a race car, no vin.
