Rebuilt 454 7.4L TBI Unit For 1987-1990 Chevy/GMC Trucks - Silverado, Suburban, Sierra

Got a 1987-1990 full-size Chevy or GMC with the big block 454?

This rebuilt TBI unit is just what the doctor ordered.

We take cores and completely rework them—cleaned up, flow-matched injectors, fresh gaskets, and all the right linkages for your truck, whether it's auto or manual.

Bolts right on to your Silverado, Suburban, Sierra, or Yukon (the full-size ones, not the S-series).

Keep in mind, the photos are examples, but your unit will be set up exactly for your application.

A solid, affordable way to get that big block breathing right again.
