My future son-in-law has a 1997 Tahoe 4x4 with a 5.7L and 4L60e tranny. The spider injection assembly has gone bad, plus the fuel lines that go to it move up and down along with their stud mounts. He's decided he wants to cross it over to carb. I'll be helping him, but I admit that my experience is rather limited when it comes to mods. I understand the transmission is computer controlled and will need certain inputs, but i don't know which ones. Can the computer be used as a stand-alone controller for the tranny? Also, he wants to completely rebuild the motor and go with a bigger cam. But looking at the specs, is it really possible to go big cam-wise? The lift looks like it will be limited by the guides in the head. Are there practical mods for this? I haven't turned wrenches in 20+ years. To say I'm rusty would be a major understatement! Any help would be greatly appreciated.
