Just changed the Pontiac over to a 600cfm Holley and edelbrock performer intake. installed a HEI distributor (had a cold that is why it sounds like HDI in VID), put on th chrome air cleaner and valve covers ( need new gaskets), just put in the new radio and speakers and all new brakes. and new 3 gauge cluster. runs much better but the carb needs to be tuned. gonna get my exhaust done soon so wanted to hear the difference.
