After attempting some badge engineering to enter the compact truck market, GM developed the S-10 and S-10 Blazer to grab market share in a growing segment. In order to keep costs down, GM robbed a significant amount of chassis parts from current G-Body vehicles, making shoehorning a Gen III/IV LS engine a simple process with our bolt-in swap systems.

From the cylinder head flange to the tailpipe, the Blackheart line is engineered to provide maximum exhaust velocity, ground clearance, style, performance, and quality.
