Engine Help Guess Specs

Hey guys, I currently have my motor out as I'm rebuilding it up, I haven't bought any fuel injectors / maf or a clutch yet as I'm still unaware of what my motor is putting out. So if you guys could shed some light on a few guesstimates it would be awesome
Car has stock bottom end 302 forged Pistons, trick flow top end engine kit (75 mm throttle body, intake with 1 inch spacer, tfs stage 1 cam , trick flow 170 heads), giant long tubes, 3 inch exhaust the whole way to borla mufflers
And a v3 sci Vortech with intercooler. (Probably gonna run 7-8 pounds) If any other information is required I'll gladly answer, thanks guys

P.s. I'm assuming 42 injectors are enough? Or no?

When you say No fmu does that mean i shouldn't use the vortech one that came with the supercharger ? I also have a wide band installed btw

I will be getting a tune the second i get the thing driving , so do you think i should buy 42 pounders ? I dont have any injectors yet

Ahh ohkay I understand now, I wasn't too sure how the fmu tied in to it, so if 42 pounders are enough , I'm estimated to be UNDER 448hp ? This is doing some rough math with all the stuff

Not to turn this in to a different discussion but I honestly thought I'd be above that in power ? Or am I dreaming
