The NV3500 will live a long trouble-free life behind the 360. I have been running my stock NV3500 behind my mild 360 for five years with zero problems. I have a Zoom clutch and the hurst shifter. You can kill anything if you drive like an idiot. My buddy killed three T-56's in his Firechicken with a damb near stock LS1. Drive it rite and it will hold in for a long time.
