Turbo Blue Racing Fuels

Race gas is like Viagra. Unless you really need it, it's not going to help you. Most people when they rebuild these old engines use a Fel-Pro Permatorque head gasket thats twice as thick as the old steel shim head gaskets and that does to tend to knock(pun intended) some compression out of these motors. You wanna put pump gas in your L72. Just put on a set of aluminum heads and Fel-Pro Permatorques and watch how that thick head gasket and aluminum's thermal effiency tames that beast down. Great way to neuter a Rat.
