MastrAssSlyr Posted July 7, 2020 Share Posted July 7, 2020 Hey, I haven’t seen anything about swapping in a 4.8 vortec anywhere, anyone know how they fit/if there is any chance of keeping my tranny? Link to comment Share on other sites More sharing options...

Pete M Posted July 7, 2020 Share Posted July 7, 2020 can't imagine it'd be much different than any other Chevy v8. Novak should have some data on it. you sure there's not one in the Epic Tech forum? I swear I've heard of someone on CC swapping one in. Link to comment Share on other sites More sharing options...
JMO413 Posted July 7, 2020 Share Posted July 7, 2020 4.8/5.3/6.0 all the same block configuration. Search LS swap. Link to comment Share on other sites More sharing options...
89 MJ Posted July 7, 2020 Share Posted July 7, 2020 @Limeyjeeper and @70barracuda are your LS/manual guys. Link to comment Share on other sites More sharing options...
Limeyjeeper Posted July 7, 2020 Share Posted July 7, 2020 4.8 has the same block completely interchangeable with 5.3. You can put an AX15, NV3550 or the NSG370. Novak have adapters. You can also put a tremec behind the LS if you want more power capability. Link to comment Share on other sites More sharing options...
