The engines are completely different. 2.8 I4 & 3.5 I5 in Colorado and 2.2 I4 & 4.3 V6 in S10. The Colorado is a COMPLETE redesign from the ground up, not a single component has been crossed over between the two (other than those god-awful seats, I can say this because I had them in my S10)
The Colorado is wider than the S10, so as far as room to work inside the engine bay there is more room in the Colorado, especially considering it is only avail. with inline style engines. Lots of room either side(in comparison to the S10), not necessarily lots of room front to back. Hope that helps.
