Thread: Build help for small journal 327

Tweet

Yep you probably will get 400 HP out of a 327. But at what rpm ? Higher up the rev range. So to put it roughly, you will make 400 with a 327 but you will use more fuel than a 383. Why ? because just by the size of the 383 stroke 3.75 " they produce their power by torque, down in the low revs. But still a high reving 327 sounds great. It's all up to your personal choice. I am building two radically different motors one is a 383 the other is a 302, both chevys, both share the 4.00 " bore. The 383 is to have fun with, the 302 is a resto and I happen to like high rpm shift changes and the car it is in only goes out on a fine weekend when finished.

PS why not a 350 ? Build them all the time for people, good motor, great motor, but I like experimenting with something else
