Mike Virant took the solid running 455 out of a 71 Riviera and had it mounted on a stand to get it better then it had ever been. First you see what it looked like before and then after it has been modified.
The result is stunning. A true beauty.

Mike, leave the hood off after mounting this engine!!!
too good to hide in an engine compartment.
