yeah you could run a 75 shot all day long if you have everything set right. 3.8 is pretty big motor for a six ive seen people run 60 shots all day on stock 4bangers. its all about detonation as long as you have enough fuel supplied good timing and spark your in the clear. and the stock 3.8l parts should be able to handle a 50 no problem. NITROUS IS NOT THE ENGINE KILLER IT IS MADE OUT TO BE!!! IT WAS FRAMED!!!

 

I MEAN NOT DETONATING
