I知 running a stand alone with a stock bottom 6.0 on c16 and wondering a max shot I can use. Currently 150 shot but I feel I知 safe at 200. Any advice?

 

Need more info on the kit. What system? Throttle plate, carbureted plate, direct port?

200hp seems to be the "safe" limit on stock rings. Others have pushed further with varied results. The throttle plate kits don't distribute well above 200.
