I'm running a holley 3310 with the acc pump tweaked
and have it jetted and spring'd for my engine. Eddy
air gap RPM manifold, eddy performer RPM cam, head
work on stock heads, don't know compression ratio
exactly as I didn't build it, but compression
tests put me about 190 psi cyl pressure.

It's weird, it's like my no 2 cyl is "off" some.
It smooths out once I have my advance set up to
about 25-30 before (yikes)checked degree on camshaft
last year when I replaced the timing cover and that
was good. There's a noticeable difference between
the old disty and this (high performance) one.
