This motor is built to support 1000whp and features 272 cams, killer b oil pan, firelock head gasket, and half inch heads studs. Fully forged internals and short block by m45 as well as brand new heads machined by m45. Long block has never been used or installed. I am selling it because I no longer want to go high horsepower. I am also willing to sell the motor in parts: $6 for the short block and $5k for the staged heads with the head studs.
