Nv4500

Has anyone ever tried a pre 95 NV4500 bellhousing on a 95 up? They say the pattern is off and i was wondering just how much off. If its not bad and i can weld and machine or drill and tap id like to put one on my 96

95 *might* work, I can't remember all the details on these trannies. But I do know they have different patterns over the years. But I wanna say it won't, and there isn't an ideal surface to drill and tap to get the pattern you need. I think the website is NV4500.com, all the info you'll need.

454 Vortec will accept any cast iron engine SB or BB bell housing.
The difference is the top center bolt and it can be left off, or whatever.
That said, the bell housing must match the clutch release mechanism. "Ramshead" or "external slave".
