Fascinating. I think the 2000cc in my '73, which was recently rebuilt, might be the last go-round with a four cylinder.
I hate to say that, since the car runs well, and it'd be kind of sad to see all that stock-ness, which I've preserved for so long, go away.
But, on the other hand...
I've always wanted a 302 instead. Thing is, some of the street installations I've seen in the past seemed a bit severe, cutting out the entire front cross member for the radiator installation and removing the hood latch; solid motor mounts, etc.
I also thought the early Pintos weren't good candidates for the swap—clearly I'm mistaken. I didn't know a radiator would fit in front of the engine compartment on the early cars.
