Hey Guys just like the Title, what should the compression pressure be for (Stock) 302 SBF. I want to have a Ball Park area when i do mine.

Thanks Matt

all cylinders being within 10% of each other is more important than the actual #s, but @150 give or take.

120 - 170 is nominal and yes for proper performance there should not be more then 10% variance
