454 Crank into 402 build 550hp goal

Hey guys, new member here with an interesting challenge. Any input/advice would be awesome.

Heres the rundown

I've got a 69 block #3955272 396 that has been bored .30 over already from the previous owner and has the heads #3931063 on them right now. I will be ripping the block bare and selling the stuff to fund my build so nothing stock will be in it. I've been told no i cannot achieve 500-550hp NA from a 402 block nor run 10s in the 1/4 mile. I've got a "oh yeah i'll prove you wrong" attitude so i've been talking with some old school racers where i work and got some advice and stuff and researched blah blah and my goal is to have a 500-550hp motor and to run 10s in the 1/4mile. I'll be shoving this motor into a 76 camaro. Yes i already know the trans, suspension and rear need to be modded but those are future plans as i'm focused on this one at the moment. So far the build i've come up with is this (with the help of a big block builder)

AFR 265cc heads AFR 265cc Oval Port Magnum BBC Cylinder Heads 3610-1 -
Single plane intake manifold
850cfm carb
he suggested a cam close to these specs (solid roller around @050 268/272 660/660 108)

454 Crank, (scat, eagle, or callies) steel crank
I beam rods 6.135
KB361 pistons

any thoughts or suggests on how to get 500 out of what i have? I'd get a 454 but people want too much for them and theres non within reasonable driving range
