Greetings All, My first post and I hope it's not too dumb a question. I have a 99 GMC K2500 Suburban with a blown up 7.4. The previous owner must of had a cooler line break and ran it out of oil spinning 6 rod bearings. I'm going to eventually rebuild it and possibly install it in my Tahoe at a later date, but for now I need to get the suburban back on the road. I puchased a 2003 5.3 complete with harness and ecm but it didn't come with the DBW pedal, TAC module or harness. I was wondering if the DBC throttle body off the 7.4 would work with a adapter on the 5.3 with the correct harness mods, and a 0411 ecm. any suggestions will be appreciated.
