Al---You could try the 87 Octane with the 9:1 CR, but expect to retard your
ignition timing a few degrees, depending on where you now have it, of course.
I'd guess you could end up with the timing at 6 deg. BTDC (set with no vacuum
attached) and the engine idling no faster than 800rpm. Listen for pinging upon
acceleration, and adjust timing accordingly.

Subject: [6pack] Compression boost
I am in the process of rebuilding my 76 motor.
I had it bored out 20 over and got a G2 cam, aluminum flywheel.
I couldn't decide what to do with the head. I just left it at the machine
shop and am going to have it milled for
9 to 1 compression.
The nice thing about the 7.5 to 1 compression was that it ran on regular gas.
Not to sure what effect the 9 to 1 will have on gas requirement;
or if I just should have bumped the compression even higher.
