racingjunk is a good place to price out or buy used drag cars and parts
I bought my old hotrod for $3000 and it was great fun bracketracing in the low 13's 20 yrs ago. If I dedicated it for drag racing, it would have gone 11's, but it was also my DD and I liked having it all original and stock, running reasonable gearing, street suspension, all steel, full interior, etc.
Fast costs $$$ and breaks parts, you can learn an awful lot and have tons of fun with a "slow" 12 sec car and not be buying parts all the time. Slow cars are way more consistent for bracketracing anyhow.
