How would you build a low 10’s street car

Yep, it is easy to do ! but it cost's. Guy's chiming in with their combo's and not really giving the actual cost's of parts and machine work. lol I understand the OP as having No mechanical knowledge and probably no mechanical ability.

Nothing in hot rodding is cheap, I've been doing this for over 40 years and it has never has been.

I have right at $16,000 in my 434, that includes buying the complete R1, Indy headed 394" engine. I sold the rotating assembly with the damper to my nephew. I still have the Indy rockers and a MSD distributor that came with it that could be sold. So realistically $15,500 in a power plant to run very low 10's in a relatively heavy car. In a well set up light weight car mid, upper 9's would be easy. All on pump 93, put two more points of compression and race gas in it and what would it run?

I honestly believe I could take 12 grand and new Hemi and run mid or low 9's in my car. Window cranks, headliner, carpet with sound deadner, wipers, heater and everything else. It's really not that hard anymore.
