I've got a 99 4.8 5speed and 8lbs boost. How much abuse can the nv3500 take...second is already tricky sometimes.

options...cheap ones? Lol

 

BlackCash on here ran one behind a 4.3 and a **** ton of spray for years. Upgraded to a built 5.3 with said spray and held up for a while. Other than that, no idea I would expect a t56 is in your future.

 

Would love a t56 shifting would be sooo much easier and faster.

 

THe NVM is actually pretty strong, problem is that you Cannot shift it fast. When you do, and ram it into gear thats when it starts to dismantle itself. A Nicely built T56 is def the way to go, and lots of threads out their on the conversion
