piston question

[GThang98]

so i started building my motor is 98 cobra short block i'm going to stick with the cobra crank but and i just order some h beams rods for it. but now i dont know what kind of pistons to run. i know i wanna run the highest compression that i can wit 91 octane (california sucks i know) but also i want a piston that is going to hold 200 shot :dancing6:??

I got a set of Mahle Powerpack Flat top pistons that would give you 10.5:1 CR with cobra heads. I was gonna run them in my 2V but with the cost of gas I am lowering my compression and going with a turbo.

they wouldn't work cause i'm going with stage 3 2valve heads

With 91 octane i would stick with a stockish dish piston( 16cc if using PI heads) to keep the C/R in the 9's

so would 10:1 compression would be to much for pump gas :dunno:

No thats about where a PI headswapped NPI is but you will need to run Supreme gas (93) if you can get it.
