We met the guys from Mast Motorsports at the GM Performance Parts LSX Shootout in Memphis last year, but we just checked in on the company web site and we’re amazed at how far they have come. Mast offers almost nothing but tech for the GM late-model, variable-valve-timing V8s. They have cams, heads, and crate engines like mad. It’s all EFI, and it’s all big power and big cubes, either NA or blown.
See it all here at the Mast Motorsports web site. It’s impressive.
