Not as good as I hoped. :(

I hate to tell you, but since you are not a professional head porter, your work may have done a lot of harm and zero good.

Best of luck.

I pulled the PSRI off and installed the original, just port matched. She's got some of the lower end back. The engine machine shop that does porting did say I did a great job and that there wasn't much improvement they could do. I think it needs a bigger bore sucking air in. Cobra cams too much too? Maybe put the stocker cams back in?

Geesh, that does seem pretty low for all of what you have. Wasn' t that a high compression block? Also what about humidity - dyno says %25 was it rainy or wet?

Did they add timing, is it tuned for 93 Octane?

Yup! 10.5:1 cr. No rain, just humid. It's volume vs. velocity and finding the right combo. Ssssssssssss.... FIFTMFW! :D Blower time!
