I bought a 71 c10 and it came with what I believe from my research is a NP-833 - A833 - NP440? Not sure what they are most commonly called in the GM family?

I plan to do and LS swap and I want to keep this same 4sp tranny? Anyone have experience with these and how much power they are good for?

I read an article saying you can use a sachs 1050 flywheel on the LQ4 and an 11" clutch Gm bolt patter.

I think the NP-833 is a 10 spline input shaft, any recommended a good 11" street/strip clutch that will take 500rwhp?
