Compression VS. Octane

I have been promising the little woman that she can have her reliable street manners and I can have a little fun too. A safety factor is just what I need for a win-win!

You can always advance the cam to add a bit more dynamic compression.

I run 9:2:1 160 Cranking PSI had milled my head .100 thousands i believe they were 45CC Pistones were .170 in the hole with flat tops, didnt mill the block. I run on 87 Octane with a good recurve , i have 12 degrees at idle and 15 Mechanical and the 8.5 V Can (17 Degrees) . I could probably run more timing but probably need to use better gas. Runs Great. You gotta calculate measure more than once, then when you think you got it figured out, measure again ahahaha
