My machine shop finally after 6 months of waiting finally got the 400 rebuilt for the gto. I purchased everything for this motor through Butler performance they where great to work with. Now it's a 461 cu in on the dyno it hit 509.9 torque lbs with 402.9 Hp have a street fighter trans w/ 355 posi rear end.Should be able to pick up the motor this next week probably will be another 4 weeks before I can get it in the car.Now I'll need to figure out how to measure the drive shaft to have it cut down. Would post some pics but it's not working
