Just finished going thru the same thing with my 77 L48 vette. In 77 the L48 had 180hp and the L82 210hp. They had smog heads [882s],low proformance cam, and dished pistons. The L48 had 8.5:1 comp.& the L82 9:1 comp. I changed to Dart 202 64cc heads,flat top pistons,RV style cam & elderbrock proformer intake & headers bumped it up from 180hp to 330hp and still kept comp.to 9.5:1 and still will run on pump gas. Hope to fire it up this weekend. Hope this helps a little and good luck.
