[6pack] Compression boost

[Alan Salvatore]

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.
