I disagree. 360 = truck motor. I can't imagine the E58 package in let's say a '79 Cordoba or something screaming to 6,500 rpm, sorry. The LRE truck may have been the fastest at that particular point but that was during a time when everything across the board was completely anemic. Even the 'Vette was like 180hp or something and was kinda heavy at 3,500+. 360 compression was never offered above 8.7:1 or so, even in 'hi-po' cop cars - the 340 was always over 9 to 1. So the 360 got some 340 parts but ended up with less hp. And hey looky there, the 360 was ever offered with a forged crank. Wonder why.
And BTW, you're nuts if you don't think a factory 340 car ('cept maybe a giant-*** 340 B-body) wouldn't SMOKE a factory 360 car. I don't think anything with a 360 was ever advertised as having anywhere near 275hp (insurance company corrected 325hp) from the factory.
As far as the OP, I still maintain that you should go with a shorter stroke engine because of it's inherently better architecture for performance. While the 360 is still an over square design, the stroke approaches being under square. Perfect example of an under square engine is the slant 6. Go figure.
