I recently put a 5.3 in my 97, replacing the vortec 350 (previous owner swapped the 4.3 out).
The transmission is a nv3500.
It seems the general consensus was use a 4.8/6.0 flywheel, pilot bearing, clutch kit and it will work with the sbc slave cylinder.
After doing part number cross references. Seem the truck slave was same as camaro and s10. So felt no need replace, previous owner said they replaced it and it worked fine past 2 yrs for me and visually I could tell it was a newer unit.
So to the point, after bolting the trans to the 5.3, I had someone push on the truck, so I could make sure the clutch was disengaging.
It did but initial thoughts. The pedal feels incredibly soft as compared to before.
I guess my question, before thinking somethings wrong, is were the nbs trucks pressure plates, designed differently, allowing a more softer pedal feel?
Cause my initial thought, in regards to the 4.8 pressure plate was clamping force. Not so much whether I should have used the 4.8 slave. As before the pedal feel was much stiffer, which I'm more accustomed to in pre 2000 fullsize trucks, all makes. Now it feels like a pedal I'd expect in an s10 or ranger, even a car.
Just thinking out loud in print. I'll go with it for now, still need finish up the wiring before maiden run but that pedal feel caught me off guard and has me wondering.
