Ah, I see. Well that explains the heads.
I had a 69 mustang 302 that I had tricked up. It was stolen, stripped, and then torched.
To replace it we bought a 70 Mach 1 with a Cleveland 351 in it. I swapped in the Boss 351 a bit later. My brother drove it over a cliff and then lived till I got my hands on him.
Like others have said, once I started working on vehicles for a living, I lost all interest in cars as a hobby.
