With a GMMG 427 race case on board . . . None the less. Our engine shop builds both motors for GMMG and Bell Motorsports, the team that won overall with Andy Pilgram driving. I sold them one of our 427 race cases last year when GM was out and they downsize the cubes, but the internals are pretty much the same as our motors . . . So, who wants to go 24HR racing with their ZL1 cars ? ? ?
