Default need help estimating crank HP for correct fuel injectors

as stated in title, im trying to figure out if ford 42 lb injectors are too much, as my neighbor will be pulling his VERY soon, and i need injectors on my build.

mods;
forged 347(stock crank, diamond pistons, eagle rods)
10.5 - 1 compression
stage 2 patriot heads
FAST 92/92
long tube headers
underdrive pulley

also estimate to the wheels would be nice with an auto tranny/ 3600 stall.

42s should not be too much...thats what i would go with

36s would probably work, but the 42s should not hurt

You might even be able to get away with 30's. You didn't list the cam so its hard to say.

oops, f14 cam(232/234 598/601 112), and doubtful on dry nitrous, also 42 lb ford injectors would be close to 50 lbs correct?
