American Powertrain Introduces New GM to TREMEC® Magnum Bellhousings

We love the companies in the aftermarket that create solutions to problems and make the lives of hot rodders easier. American Powertrain is one of those companies and their products prove it. The company has just dropped a new one on the world that we KNOW people are going to be excited about. This new GM to TREME Magnum bell housing is great for anyone running a big or small block Chevy OR a Buick/Olds/Pontiac engine. Yes, it works on both!

This bell housing will take your TREMEC GM Magnum transmission or a Viper T-56 and make it nestle right up to the back of the engine the way the hot rodding gods intended. The casting is super thick because they know you are making horsepower and you need the strength. This is a great piece for anyone who is not in need of an SFI certed bell housing for racing.

Here’s the full story!

    “Buick, Olds/Pontiac” is not an “engine”, how about “BOP” trans bolt pattern.
