SPEARTECH OFFERING LT5 CRATE ENGINE WITH 10 SPEED AUTO

Why Doesn’t GM Offer This Combo From The Factory?

It seems obvious that General Motors would hook one of their most powerful engines ever, the 755 hp LT5, up to one of their best transmissions, the 10L90 10-speed automatic. But, like some of GM’s other recent questionable decisions, you can’t get the C7 Corvette ZR1 engine with the Camaro ZL1 transmission from the factory. That’s where Speartech, a LT and LS engine swap harness specialist out of Anderson, Indiana, comes into play. They are offering a complete kit for the LT5 crate engine and 10 speed auto for your engine swap dreams, as discovered by AutoEvolution.

It does come at a hefty price, however, given Speartech is the only company that have been able to pull this pairing off. All together, it’ll set you back $37,500. That could get you a pretty good muscle car from either of the big three, but you won’t be getting anywhere near the 755 hp this engine puts out. Speartech says they’ve extensively tested the setup to be the first and only place you can get it from. They used a Chevy C10 pickup as a test bed for the engine and transmission, and it had over a year of development.

In the package, you obviously get the LT5 crate engine and 10 speed auto, but it’s unclear whether they use the 10L80 or stronger 10L90 transmission variant from the Camaro ZL1. Given the hp output, we hope it’s the latter. In addition, Speartech supplies buyers with their complete custom harness setup, and a “swap friendly” intake system. For additional costs, customers can add a Drive Junky or Holley front end drive kit.

The kit is shipped completely ready to go, so all you have to do is drop it in your project and you’ll be  ready to turn the key and feel what 755 hp can do. At $37,500, it’s as much as a Camaro LT1, especially when you still need to supply so many other components for the build yourself. Still, a Corvette ZR1 is the only way to get this engine from GM, and that will cost you significantly more. And to top it off, GM won’t sell you this pairing in the first place, something they should definitely consider.
