Had a 67 Mustang with a .60 bored over 289.Now I know the 289 is NOT concidered a muscle engine but they were the toughest block made.Ran an Edelbrock intake manifold and an MSD ignition with the holo distributor.Holly 750 double pumper and a hot cam.It was doing 350 horses on paper and it did that on the street too
Damn thing handeled for crap at speed tho....sigh.
