These 360's (71-74) are excellent blocks. They are much stronger than later 360's. They are also a bit more sought after by drag racers because of the thicker cyl. walls and main webbing.
These are good blocks to turn into big bore strokers.

Al, I have an old truck, 1971, that has one of these. If you're ever in the neighborhood we can throw it in the back of yer truck. It has something like 60,000 miles but it needs an overhaul (4" crank
).
