2010 Colorado LH9 5.3 Engine?
#11
I got the site to open and here it is:"media.gm.com/us/powertrain/en/product_servic/2010/gmna/10truck_us.htmn" if you knew how bad I type you would appreciate what that cost me! I believe if you look at other 5.3 engines before and after VVT you will see about a 30 hp increase. It also shows LH9 will have 8/4 technology ! Ben
