We ran each set of heads with 91-octane pump gas then backed up our findings with a load of Rockett Brand 118-octane fuel just to make sure that there was no possibility of detonation that we did not discern audibly or through checking spark plugs. Renegade SB Ford Aluminum Cylinder Heads are Designed to be a Fantastic Flowing functionality head whilst becoming cost-effective. Of torque, 9.five:1 compression ratio, Ford lightweight aluminum block, Mahle forged-aluminum pistons, Dependable supercharged overall performance on 91 octane pump gas, Involves crucial supercharger kit components , These are on a build to order. These reasonably priced AFR 210cc intake port little block Chevy angle plug cylinder heads are available in two stages of overall performance.
Bush Performance modifies 351C heads for installation on the 289/302/351W block, eliminating 1 water passage even though making yet another.
