In the days of Pro Street dominance, the baddest of the bad had a big blower with two Holleys on top of a big block under the hood of whatever it was they built. Sure most of them were just trailer queens that cruised the fairgrounds and usually never even did burnouts, but man they looked incredible. And when B&M came out with their 420 Mega Blower, it took the B&M Superchargers brand to a whole new level. This thing was big, like almost as big as an 8-71, and had the looks that were perfect for the times. I always wanted a big tire 1969 Camaro with a big block and a supercharger. This one would fit the bill perfectly.

And it comes with the Holley Carbs, a Dooley scoop, and all the pulleys. I’m sure it could all use a going through and cleanup, but I’m sure it will all work just fine. Back in the day Richard Holdener made more than 720 hp using a Mega Blower on a 489 inch big block Chevy, and that was without pushing it.

Someone should buy this and make a cool Pro Street car even cooler.
