It was a 351M but I replaced the crank with the crank and pistons for the 400. It will make it a 408ci engine. Custom 11:1 JE pistons, Crane cam, Edelbrock intake, Edelbrock carb. Still in the works so no headers yet.
Drivetrain:
It has a C6 trans, NP205 case, eight-lug Dana 44 front and Dana 60 rear. It has 3/4 ton leaf springs in front and rear. Front has been converted to leaf spring.
