It's too bad GM didn't develop this engine platform any further. If it were to make it into the Colorado, it may have made all the difference. The time to do it was when Larry Ragland was screaming through Baja in his Trophy Truck. GM had the chance to build a killer SUV based on the Atlas, but instead built a plastic bumpered disposable mall crawler. Their answer was the H3, and I'm not going to go there. The drivetrain is the best part of the TB/Envoy platform. Personally, I think the interest has peaked and is on the downhill slide. People like us are the only ones that really care. On another note, how much aftermarket does there need to be? The 4200 already will outhorsepower a stock small block and it will fit into just about anything. When you compare numbers that EFI-DIY, Limequat, and Autoroc are getting out of their engines and compare it to the Ford Lightnings and Mustang Cobra's of a few years ago. The 4200 more than holds its own.
