Budget drag car… B-Body or A-Body?

I know some B-bodies weigh close to the A-body. I guess a majority of my curiosity with the B-body platform are frame stiffness, available rear ends with lower gears, and big blocks.
I agree. I had a 1965 plymouth Belvedere II 2 door hard top. All steel with a fiberglass hood and scoop. 440 with 727, Dana 60 with a 10 point cage. Car weighed 3420 with me in it. Sold it and after on built a 73 Big block dart. All steel with fiberglass hood scoop. 8-3/4 rear. 440/ 727, no roll bar. I did remove the crash bar out of the front bumper.. the car weighed 3520 with me in it. I couldn't beleaeve the dart was heaver than my 65 plymouth.
To the op good luck finding a A body for $5000 that doesn't need another 5000 just to get it road worthy. Lol
