My '66 tests at 195 psi or there abouts with a Comp Cams 268 HE. that's 218/218 at .050" lift. It was set up with a 9.5/1 CR. I run a total 45 deg. of advance, all in by 3000.

The reason it needs that much is because I'm using 351W heads which are not really very efficient. When I get my new TFTW heads in (as I type), I'll start with 36 geg. total advance.

So far have had no detonation problems using 92 octane pump gas. Crossing my fingers with these new heads.
