I live in the Northen part of BC Canada. I have to drive my car a long ways to get to any meets, shows or gatherings. My car is a 65 Coronet with a 68 HP 440 Engine. The compression is the stock 10:1. Car should run on 94 plus octane. 91 is around here a little bit, but 94 is hard to find. Mixing with av, race fuel etc is not practical as I frequently drive this car 8-12 hours round trips. My question is this: Is there a head gasket that I can use to bring the comp down so it will run on regular pump gas? Not only because of the cost but because of the detonation issue that I run in to with not being able to get a consistant octane level of gas for the car. Or is there another economical head that I can switch to to be able to run this thing on pump regular. I realize that I can turn the timing back but this limits the power of the engine etc. and hampers the gas mileage. Currently it get about 15mpg on the highway, I would like to get the same if not better. The motor is running a comp cam, headers, eddy performer intake, holley 670 street avenger, new dizzy from 4 seconds flat with vacuum advance, MSD box, 3 inch exhaust with glass packs. 3.25 gears and a 727 auto.
Any ideas on the cheap would be good, I have spend a sh*t pile of money on this car already and I just want to be able to drive it without hurting the motor.
