I'd like to find some more out about this stuff....i'm starting to question my spec sheet, although for years people thought it was 10.5:1.

9.5 it is, damn I gotta find where I got that sheet from. I cant remember. I know now why I can run so much timing on my truck. I didnt think it would be able to take as much if it was a 10.5:1. Thanks for bringin that up, I woulda keep goin on thinkin it was higher!
