i have a ford motor in my pickup, and a chevy in my car, both are from the same age, both i did the same amount of work on (new carb, timing, big airfilter, carb, and headers) and my car lasted me about 2 months before i blew the motor in that, and my pickup lasted me 5 years before i blew it, and its not even fully blown i just need a new lifter, my cars fucked though. both motors had about the same kind of driver, and about the same length on the road. and i raced my pickup, and my car both, and the ford beat the car by a long fucking shot. fords do own! '68 Shelby Mustang! or the '68 boss 427's with the overhead cam FE 427 putting out 600 to the ground from the factory!
