I am looking at a GMC Suburban with a Whipple supercharger. I notice that Whipple isn't selling kits for a Vortec 5.7 anymore. Didi they have problems with the Vortec kits or engine management? Should I stay away from this vehicle?
Thanks

The only reason we are not selling the 5.7 (350) and 7.4 (454) kits any longer have that size/style of ccompressor. When we were making this kit, we were purchasing our compressors from Lysholm. In 2004 we had a falling out with Lysholm and had to start developing our own brand compressors. We started out with the W140 (2.3L) and after about a year of no sales, we had to get back into the market. We said we would just start out with the newer (1999+) kits and go from their. We had not had enough demand for the 350 kits using the 1.6L compressor so we did not make one. Because we are so far into the years now, we are not planning anything for the older vehicles. Sorry

hi,
because I have the major parts of this kit I search parts .
you don't produce it anymore but do you have parts like wiring hardness, Interface computer, or rebuid kit ?

if not, I think I can rebuild if I find schematic of wiring and interface computer.

do you have something like this?

thanks!
