I just got a tunnel Ram and I dont know what size carbs to run on the street. Any help will work at this point. My motor is a 90 302 block with the heads ported out and 1.7 crane rollers. I turned my pistons around to bump it up some. My cam is a Voodoo .227/.233 dur and the lift is .522/.538.

you want to keep the intake velocity up as much as you can, expecially with the tunnel ram intake. i would use a pair of 390cfm holleys, and no more than 450 cfm holleys. that will give you a total of 780-900cfm total airflow capacity which is plenty for your engine combo.
