GM will never build it. its against their "we cant build anything high performance because it might actually compete with the corvette or there isnt a market for high performance" rule

I had a 3.5L/5-speed regular cab power nothing truck that was just an absolute blast to drive. I would put it up against a stock 5.3 silverado anyday. The big issue was traction, coming off the clutch meant wheel hop and big time. Counldn't make a 1-2 shift at WOT for all the wheel hop. There was a ZQ8 version that ran consistant mid 9's in the 1/8th mile. www.coloradofans.com is a good website for the colorados

As long as your not just pulling that out of your *** that pretty much sells me on the Colorado....I can handle that kind of power, that's pretty decent actually for a 5 cyl

I'll be going strictly turbocharged....as long as I can find larger injectors and HPTuners supports it within the next 6 months I'll be golden. I'll fab up a header if I have to but I'd rather use the stock manifold if I can for now

Do they have cams yet for the I-6? If so maybe a machine shop could cut off the lobes for the back cylinder. Just a thought.
