The 1997 GMC 350 (5.7 L) is a Vortec motor with fuel injection. It was first used in 1996 and I believe motor through 2000 are the same as yours. Older motors use a throttle body intake with a carburetor. You are supposed to be able to take the intake from your old engine and use it on the older 350 blocks...but I have hear conflicting stories about bolt holes lining up to allow this. I am not sure what the issues are with newer engines, but I imaging it ties into computer and wiring conflicts. I am not a mechanic, but I am in the middle of searching for a replacement engine for my 1997 Sierra extended cab...mine gave out after 218,000 miles. This is what I have learned during my search. Good luck, I have found that when one becomes available it is snatched up quickly. Scrapyards around here are asking $750 for a 100,000 mile 350 Vortec.
