I was recently issued a chev colorado as a company vehicle. I must say I am the reciprocal of all previous posts. 4 Door, long bed, not sure what the gearing is but I am pulling down 25-29 miles/gallon on the HWY. Last week I drove 500 miles from WA. to MT over 2 MTN. passes and avg. 29/gal. This vehicle is made for the HWY. 1750 RPM's at 85-90 MPH. Plenty of torque for passing and hills. Over 2200 RPM's is useless, get your foot out of it and let it shift gears. Would I consider it a donor/replacement motor---NO----it is what it is---I keep waiting for a cylinder to walk by and join the team since I feel short a team member. It is a capable motor but probably not one to pursue for any type of performance capability. Volvo has been using a 5 for years with excellent success--- I just don't see enough upside for this to be a well supported engine. I doubt you will see a thread like the 4.2L (Personal Opinion)
