this spring I'll be going to Epping NH for the first time to race and was wondering if any of the more experienced guys out here might have an idea o0f what my truck should run

its a 454 stock bore and stroke
3904390 heads decked and 2.19 1.88 ss valves done 94.7cc chamber
jones solid roller 708 int 710 ex 268 272 @ .050
performer rpm slightly opened
holley 750 double pump
full tube headers 1 3/4 pri 3" collectors
its a 53 chevy pick up 2700 lbs
f@#d 9" rear 4.56 gears 31x18.5x15 mickeys
four bar set up on the rear
th400 reverse valvebody 5000 stall
I know its not a lot of info I'm not looking for exact ets
