Budget drag car… B-Body or A-Body?

How fast are you wanting to go ?
5 k if you already have a car, 5 k isn't going to net any b-body worthy of drag strip duty, not to mention every single item you had to buy now is more money.
I have a $400.00 dart I got 4 years ago luckily, I'm shooting for low tens... so I got $5000 in heads crank pistons & rods, $1000 in rockers. the stock 400 engine was $400.00 & machine work $2500.00 with ARP main studs. Shoot, oil pan was about $500, intake $350.00, headers $850, way to much to list. Rear suspension $800, front $400, rear end $1900. I haven't built the trans or got a converter and I'm guessing 3k minimum
Haven't even bought rear wheels yet $900.
I'm forgetting all the small parts which are easily 1000 and the probably 4k more to get the car ready to go down the track.
5k is a dream, not today & definitely not from scratch. Some will say it can be done but unless you're getting mostly free parts, it is mathematically impossible.
Unless you want to drag a 66 4 door with a 6 and 3 on the tree.
