with a sufficient fuel system, and correct tune... I could see a 200 shot working safely.... as long as your drivetrain holds up.

 

I spray 170 all the time, & 220 on occasions. The 4.8 is petty tuff, it has a 6 bolt main, an extra cam journal that is also much larger than the old school small block. I ran 12's with just cam, headers, valve springs, & some old school cheats.(smaller diameter tires) & 170 shot.

The like high rpm's......good luck
