help pick a cam

I know this is bench racing, but I love it.
the 340 is over .030 . so, its a 345 now.
cast crank, forged rods with the works,10to 1 J&E flats with silvolite rings,
clevite bearings, hv oil pump.
the motor has 360 heads with 1.88 intake valves, 1.60 exhaust, I have the 273 adjustable rockers and bad asz pushrods . the cam is .480 on both and 236 dur.@ 50. I bought an LD340 intake. also have mp elec. dist. and chrome ecu.
#1 what size carb ??
#2 what kinda cam will go well for street and some 1/8 th mile draggin?
im planning on adding eddy heads, and was told not any biger than .530 lift. I want to be able to run pump gas without a pain in my a*$#@%. all advice is welcome.
thanx, joe
