Re: rebuild or not??
Rebuild the 400. Those 400 motors are sweet and getting rare to find these days. You'd get more torque from the 400 and I would think more HP too if you chose the right cam/pistons. I've never been impressed with the 327's torque but they are a quick revving engine great for cars such as the vette. I had a 327 in my old 80 GMC k20 and it was a dog in that truck. RPM's had to be really high to get some power.
It's kind of funny you brought this up. Was talking to Jay (dynoshop owner) and he had a freshly rebuilt 327 on the floor wrapped up in plastic from the machine shop. He asked if I wanted to buy the 327 and I said, "no, but if that was a 400 I might consider". He said, "hell, if that was a 400 SBC, I wouldn't even be selling it...."
