Motor City Billet Bullet aka 670 cid Hemi Engine

Today's engine is something special. It's made 100% of billet aluminum. It required new dyno and turbo technology to be made in order to achieve its performance goals. It took eight years to perfect and is a barrier-breaking engine combination. Moran Motorsports had an initial goal of 4,400 hp based off of turbo technology at the time.

Find out what went into this incredible build and how much further Moran thinks he can push its limits.
