Nothing to add, just a good post I want to follow!

On a different starter note had a friend with a high compression 327 in a 67 vette, who couldn't get it to turn over when the car was warm. The exhaust would heat up the starter and the resistence of electricity I guess would increase. He solved it by getting a high compression low profile starter. Now it works like a champ. Didn't drive his car for a year because of this problem!
