So evidently, according to every wrecking yard I've spoken with, and all of the articles I have read online, I am trying to re-invent the wheel with this set up I am trying to run. I have an 01 fuel injected 6.0 Chevy V8 out of a 3/4 ton pickup. I am trying to mate that to an early model NV4500 (1992/93) and have had no luck trying to find the correct bellhousing. I am under the assumption that since the bellhousing bolt pattern on the rear of the block is the same as all SBC engines, that I just need to find a bell from that year truck (92/93) that was equipped with the 5.7/NV4500. All the wreckers keep telling me that it won't work. I need to get a bellhousing off of an 01 truck that has the NV4500 but they don't understand that the NV4500 changed bolt patterns around 95, so that won't work. Surely someone has ran this setup, using all factory parts. I just need to know that it's possible.
