472 Hemi's dyno run

What started as a leaking rear main turned into an engine tear down for a 1967 Plymouth GTX.

Street Legal TV reports that the key to the reconstruction of the 472 Hemi was a 4.150-inch stroker crank, in addition to Mopar performance 10:1 pistons and a small roller cam from For Hemis Only. It’s also equipped with a set of Stage V heads and an intake manifold topped with a pair of 650 cfm Edelbrock carbs.
