the compression calculator with a factory 389 bottom end and the 6X heads puts it at 7.6:1 compression and I run 91 and 100 octane mix till I sort out the timing and general tune

Hey, I see that AZ plate! Are you in the Valley, or elsewhere?
Mad respect for doing all your work! I hope to join the club some day.

Awesome, keep an eye on the a/f gauge till you work it out. I started at 6 psi. You will get different opinions but I like it safe . 11.7 is my roof past that I lift just in case!

Wow, stock bottom end (cast pistons and stock rods) at 9psi. What kind of power do you think it is making?
I'm in Glendale. |

What did you do for exhaust? Custom headers or manifolds flipped around?

thanks George and macho it comes up where the oil filter goes and goes down in the same area. That's why my down pipe is only 3.5" I made an oil filter relocation kit and the filter and housing are now right in front of the passenger front tire

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
