Budget drag car… B-Body or A-Body?

Late year 8-1/4’s are big bolt and owning a B body is not an automatic big dollar expenditure. There “Going slower” is only weight related. While the extra wheel base length is a draw back, it’s minor. You just work with what you have.

Going fast cheap is an exercise in thinking as well as what you can afford.
8.25 are also c- clip, no thanks.
B- bodies are usually more money than a-bodies and the price gap isn't small.
The op is trying to build a drag car for 5k budget, or at least hypothetically & yeah a b-body is up above the weight of a full caged big block a-body, not the best place to be start. I will say it's easier to do stuff on a b-body like work on it, but a-bodies we're higher production, so cheaper. Except the prices aren't cheap by anymore.
