cutting out going up hill?

thanks for the ideas, but it has a new fuel pump, new fuel filter, i,m sure the sock at the pickup tube is long ago history. i'l try to do some vacuum testing, replace the hoses at the tank and pump, .... i. ve seen some people on here refer to slant six dan or someone as a good source for rebuilt carbs.
back when i did alot of work, i'd have a fresh 340 or 440, buy a new edelbrock, but have the old dist. i found htre carb or the dist was always a problem. i would always replace the tank pickup and get a repro fuel line, and all would be good. but i had more $$ to spend back then!!! and parts wern't as high! i will continue on. thanks.
