Our friend Richard Holdener has been hanging out in New Mexico with Courtney and the guys at Cad Company, doing some killer dyno testing on a 500 cubic inch Cadillac recently. They put together a stock rebuild and then started putting more and more power parts on it to see just how much power it would make. At 500 cubic inches, these are not little engines, but they were made for cruising but not big horsepower. With that said, they  do make amazing torque and very respectable horsepower. But in the previous videos you saw that a camshaft, bolts ons, and testing proved there could be some real gains in power on this thing. Well what if we told you that there was more to be done?

Did you know that there are big valve aluminum heads available for the 472 and 500 inch Caddy?  Well there are, and they can support a lot more power. Of course there seems to be some question as to what size carburetor is going to be needed in order to support that power as well, and since a ProCharger is soon going to find a home on top of the Caddy engine then we have to keep that in mind as well.

Watch these latest two videos and we’ll have ProCharged Caddy power coming soon too!
