Q & A
Speedway Motors and Classic Trucks called on GM Performance to power their ground up rebuild of a 1952 Chevy truck that was built in celebration of Speedway Motors’ 65th anniversary.
The engine is a really important part of our T-Bucket so we asked a few friends to help us break-in our new 383 Chevy Stroker Blue Print Crate engine. As we’ve found with a lot of the guys that work around here, they were very happy to help!
Getting the power plant in place

A brief overview of the location of small block Chevy's ID stamping, as well as links to decode your motors' history.

There are a lot of options out there when you're ready for a replacement performance crate engine. But if you compare the competition to BluePrint Engines, you'll find the value is hard to beat.
