Suprisingly, a lot of pintos live on as race cars. There are becoup amounts of speed parts for the ford 2.3 four banger. The local mini-stock class is probably 95% pintos, 3% mustang 2, and the rest are imports.
For those old enough to remember the V8 vega craze, I was always suprised you didn't see more V8 pintos. A 302 was a bolt in deal with their crossmember design. No cutting, welding , or hacking required.
