Currently one of the most popular engines to drop in a Street Rod or Muscle Car, LT1 V8's were standard equipment in 1992-97 Corvettes and GM F-bodies with Aluminum heads, and 1994-96 SS Impalas with iron heads. These engines came factory equipped with an advanced Sequential phased, Tuned Port fuel Injection system, and new cylinder heads, giving them a conservative 30% power advantage over their small block predecessors, plus a wider operating RPM range.
This gem of an engine fits the same motor mounts and bell housing as the traditional small block, so, is an easy upgrade from your present small block.
Our LT1 harnesses have injector branches that run down each side of the intake manifold for a factory clean look. They’re available in several lengths and layouts for different stock replacement and retrofit applications and use a re-programmed GM ECM with full diagnostic capabilities.
Howell also has all the LT1 support accessories you need including MAF, MAP and knock sensors, fuel pumps, air filters and service manuals. Backed by 23 years of experience, Howell is there to help you with all your EFI needs.
When ordering, please specify emission, fan, AC and VSS requirements for your project and we will create the LT1 harness that is right for you.
