It was in the 400 I had in a '62 pickup. The 400 is also in the garage torn down because of a busted valve spring. I was going to rebuild it and put it in the Mustang, but I've decided against that idea. Someday maybe I'll find an old truck or something to put the 400 in along with the Isky and 2 fours. BTW, the Isky was in the 265 that was in the '36 coupe when I bought it but the engine had spun a rod and we short blocked it out. I didn't know about the cam until I went home for my 20th high school reunion in '81 and my step father had it in his shed. I'm not going to try and rotate the earth, but I think it will make for a good cruising engine.
