Firewood truck
Newbie
Hello everyone. I am gathering parts to get ready to do the engine swap in my beater. My truck- '88 K2500 6 lug, 5.7 TBI, SM465 trans. My donor engine is from a '98 K2500 8 lug, it was a factory crate replacement engine that has about 55K on it. I have snagged a GM performance intake so that I can retain the TBI. My plan is to just use the GMPP intake, swap over the TBI distributor and simply not plug in any sensors that the Vortec used that I don't need. The Vortec engine is just basically becoming a long block to be used in the TBI truck.
My big question is about the Y pipe on the TBI engine- does it physically bolt up to the Vortec exhaust manifolds? I've read a bunch of threads that skate around this question, but never see a hard answer about if it will or won't physically bolt up. I see the "dual" down pipe setups in the Walker exhaust catalog used on the K2500/3500, but then I see a single Y pipe on some K1500's that have a different p/n then those used on the TBI engines. I don't want to spend any $$ for the "correct" Y pipe if the one that I already have will work. Thanks for any info!
