360 Core Questions
Well first there weren't any 360's in the 60's and they are rare but 71 was the very first year for the LA engine (360), and they only came in the trucks and in 72 they were offered in passenger cars, they also came (in the early years) with 340 water jacket coreing 71-72-76. They tell me that they can be over bored .100 as they came the same as the 340 jacketing. But do have the engine sonic check to know for sure and your done.
