Speartech 69 C10 LT4 8L90

Description
 
We bought this very clean 1969 Chevrolet C10 Truck as a way to develop and test the new Gen 5 family of Chevy small block V8s. We have been offering standalone swap harnesses for the Chevy Gen 5 V8 since 2014, but wanted to put all of our research into action and make sure we have a test bed for our products to deliver the best customer experience possible.

We got it as a very nice running and driving truck with a stock Chevy 350. We quickly ditched that engine and transmission and replaced it with a new Chevy Performance Supercharged LT4 crate engine and new GM 8L90 8 speed automatic transmission. BRP Hot Rods mounts made for quick work of getting the LT4 in place. A Rick's Tanks gas tank and Sixth Gen Camaro ZL1 fuel pump handles the fuel delivery. We had a custom driveshaft made locally and had Speedcraft Prototypes modify the factory 69 C10 shifter mechanism to mate up with the 8L90 transmission to retain the factory column shifter from the 69 C10. Dakota Digital gauges found their way into the truck, and provides all the data we need in a stock appearing setup. Our gear indicator lets us know what gear we are in at all times.

Check out the video below for a quick overview of the truck as it is currently. Keep an eye on this space, more updates coming soon!
