Dual 850 double pumpers?

well i guess what i really want to ask is would two 850s still function well on my combo which is 505" RB 10.5-1 compression, cnc ported edelbrock heads flowing 330 cfm at .600 lift, solid flat tappet cam 254/260 duration at .600/.615" lift, 4000 stall converter, full manual valve body, 3.91 gears and 28" tall tire

the plan is to sort the build out with a victor intake and a single 850 dp i already have and then when the time comes switch to the tunnel ram.

if two 850s would work well id just purchase a second one but if theres some reason it'd be too much airflow id happily buy two used 750s and rebuild them

like i said i just never see anyone running dual 850s and was wondering if there was some reason they would not work or tended to be troublesome
