This is an excellent motor. The only shortcoming of the motor are the heads. they are very restrictive. Do a machine shop rebuild (rings, bearing, light hone and a gasket kit and new oil pump). Install good heads like AFR 165 or Trick flow, edelbrock and you can get 300 rwhp with a stock short block and mild cam. Thats what I did. These motors are very reliable near indestrucble below 400 fwhp
