I had a 67 Valiant with the 170. Very sweet car, but it got a wrist pin knock.
Swapped in a later Super 6 from a truck and it was a toad. Couldn't get the thing to
outrun a taxicab, fuel mileage went in the toilet, just a bad match.
I should have fixed the 170. I would still be driving that thing.

It may be ugly, but it sure is slow.
