Where to go next? Low 11's high 10's??

that's easy on a Chevy, parts are a dime a dozen, blow it up get more parts brand new. That nitrous part isnt, I don't understand it & for my build I don't believe mopar big blocks hold up very long with that "SLAPPED ON" kit lol. See thru block is a **** outta luck scenario

I ran up to a 250 shot cheater kit on my stock '71 340 motor with no issues and also on my original 440-6 motor up to a 175 Big Shot kit with external oiling, no probs at all with forged pistons and a good fuel system for the NOS, I windowed a so called pro built s/roller 440 NA motor I bought that had an internal oiling system on it though, all I got out of that were the heads/cam and rockers, took me over a year to pay that off.
