Factory Magnum Heads

Booby, Those older magnum crate motors arent anything special either. Just a nice Hy roller cam 230/[email protected] and a single plane M1 intake. The heads have different springs but other wise are stock and the short block is same as a production truck motor but with upgraded speed Pro pistons.

Nice motors, But not fancy and hardly worth the $5000, all though the newest version does have the magnum R/T heads
