True HEI distributor conversion thoughts

All,

I did change out the Vac Adv to the one listed below. I don't run ported vac to my dizzy and use straight vac to help keep the engine cooler by supplying timing at idle. It's non adj but fits into the range of operation that I needed based on this tech article attached. If I remember the mech adv on the Ship White is 20 total, so if I recall I'm now at 54 total timing with everything all in around 30. I have a mech adv spring kit to use this spring if necessary to fine tune the new engine but with 10.2-1 compression the curve is probably safe as is. I run 93 Sunoco and no light load pinging with the new vac can.

BTW my HEI is from Skip White.
