We never had time to dyno the motor. The owner was in a hurry and wouldn't take an extra day to dyno it. As far as weight of the car I would guess some where around 3600 #s. I was just asking about to dyno to see if this motor would even come close to making the power your thinking it might make. I haven't personaly messed with mopars in a few years but I don't ever recall 360s being hard to find, I understand 318s are everywhere. I always had a hard time finding 340 blocks. There is just no way I would turn a stock 360 crank down to 318 mains. As far as stock mopar a motor heads go I wouldn't waste the time doing a valve job on them if i was wanting any kind of decent power. Cylinder head technology has come a long way in the last 10 years or so and prices have come down to not use new heads. I just couldn't justify building a smaller, weaker, less power more expensive motor.
