10,000 miles isn't nothing, I be sick if I knew my engine was good for only 10,000 miles. Come on guys, I got over 4,000 miles on my rebuild 340 I got last summer. Got drive these cars, life is short, people used to drive them year round
Plain and simple, the SMB was not design for a 4 inch stroke crank. Maybe it can work, you would think in the crazy 70--80's if it was easy it would had been done. Supercharging what was in back then
least the guy is honest and says up front 10,000 miles is a normal life of a 4 inch stroke mopar, those pistons have very short skirts, pistons rock and rings lose their seal, 10,000 miles seems about right to me.
W2 heads are the way to go, why isn't eddy making them, IDK. Back in 1979 Hot rod got over 400 hp out of a W2 head 360 but it had only 8.5 to 1 compression. Was a factory fresh short block 360 that they put in the old hemi cam and W2 heads.
