I am currently building a 454 chevy big block with a forged crank, h beam rods, forged pistons, roller rockers, hydraulic roller cam with about 5.70 lift, 8.0:1 flatop compression, large oval port heads w/ 2.19 valves, 8-71 weiand blower running about 8lbs of boost. This will be in a 70 chevy nova. It will be used for street and some strip use. Any suggestions on what size carbs to use? Also, is there a formula for carb sizing with forced induction? Thanks!!
