My first car was a 56 Customline 2dr. post. Go pre 73 351 Cleveland, they scream and get mileage. Best motor Ford ever made,,, just like Ford of the past, if it works can it and go on to the one that gets no mileage and has no power. AKA 360, 351 Windsor. The Cleveland is a direct copy of the most excellent big block Chevy, but lighter and loves the high RPM's. Do it man, you'll love it. Use 2 barrel heads and a crane high intensity cam. Be prepared to knock down any late model Mustang with ease.
