I have gotten such good feedback from this site on all things Ford so thought I would throw this out there for some of you big block guys. I just purchased a 67 Fairlane with a 427 side oiler, 2X4's etc etc, which has 12.5 /1 compression. Obviously this engine will not run on pump gas with that kind of compression. The previous owner has been running race gas, I think 110 octane. This was an old 60's era race car but the engine was rebuilt in the late 90's and the 12.5 / 1 pistons were installed at that time. The car is street legal but I need to get the compression down or continue to run race gas at about $8.00 a gallon. I will never race the car again but will take it to car shows and cruise-ins. Can I run 100 octane av-gas safely? What about octane boosters? Regarding head gaskets; are they available, is it even possible and/or is it advisable to run thicker head gaskets to reduce the compression? I remember "back in-the-day" hearing about running thicker head gaskets to reduce compression ratio. It may take a mighty thick head gasket to reduce the compression enough to be able to run pump gas.
I do not want to replace the pistons, but removing the heads would be easy if this is even feasible. Any thoughts or feedback greatly appreciated. AND, I DO have a 66 mustang also. There is a Fairlane website out there but I have not found a forum to answer this question. Any advice appreciated.
