Hey everyone! So i've been looking for a new motor for my 35 ford....I was poking around on craigslist and came across a 302 motor with a c4 trans for $100......i was a little skeptical about the deal at first, but i ended up driving out to take a look at the motor anyway. Well after a quick lookover, i ended up buying the motor. The guy i bought the motor from took it out of his 68 mustang, but he said that the motor originally came from a 79 mustang. He also told me that the trans was slipping but the motor ran good before he yanked it out. Apparently he rebuilt the motor a few years back and he said it should have about 300-375 hp. Here in lies my question... i know that these motors are about 140hp stock....how do know what upgrades, if any the motor has internally? Additionally, considering that i don't 100% that the motor runs.....i'm going to have to check everything out. I don't really know what to look for aside from doing a compression test. Any help/pointers would be greatly appreciated. Thanks in advance!
