This is for my drag build


Its kind of my budget build so every dollar counts goal is to have it running by Christmas. And next year f1a.

Any who its a 3v motor I'm rebuilding. Frpp intake cams will changed when the blower goes on. Head will be stock until blower if at all changed. And eventually go to e85

10.4:1

Vs

9.6:1

Price dif 40$

Thinking 10.4:1, let's hear it.

Wouldnt the lower compression do you more good since you're going to put a blower on it?

3v' s do not like compression or at least....thats what the buzz used to be. This may have changed, but last I knew.....3v's dont like compression. I dont keep track of 3v's anyhow......im talking out my butt. Just ignore me.

10.4 is perfect for N/A. You will need to run race gas or E85 once you go FI.

9.4 will till allow you to run pump gas once you go FI

Everyone who pi swapped has ran @ 10.4 at some point. Good gas and good tune goes a long way even if you boost it the high compression won't hurt especially if it's a centrifugal.
