What would it cost to have 7.50 chrome Molly race car built by chassis shop

Try calling several good chassis shops and see what they offer
I've seen bare welded chassis offered from around $10,000.00 and up as well as complete finish car minus motor, trans, paint, electrical and plumbing for around $75,000.00
Are there any good local shops near you?

All depends on how much work it takes. A chassis shop can knock out a "cookie cutter" type of chassis pretty quickly but something full custom that requires them to measure every bend will cost a bunch. You didn't provide enough information in your post to provide you with an answer.

i've found it's always cheaper to buy someone elses project. If it were me, I'd find a Chev or Ford bodied chassis that you like, change the body to the Mopar you like. There's heaps of Ford & Chev roller racecars for sale, choose the shape that matches your ideas.

All good points made. A mild steel build will be cheaper than a chrome moly one. A strut front end will probably set you back more than an A arm setup. If you buy a used chassis, make sure that it has been certified fairly recently so that you know it will recert. It doesn't have to be current, but within a reasonable amount of time, so updating an older chassis won't be an overwhelming amount. A 2x3 box frame would be cheaper than a full round tube, but probably would not be able to upgrade to a 6.0 chassis down the road.

It really depends on what style "chassis" car you want. A big tire body shell on a chassis will be less than a 25.3A stock floor "ship in a bottle" small tire kind of build.

Kind of a loaded question. Will depend on how much work the shell needs before they can start bending tube. A Moly 7.50 car has a lot of tig welding to take care of, and that takes a lot of time. Spending 15-20K is not out of the question.

The Factory Stock Shootout cars are required to be 7.50 certified. Looking up their chassis builders would be provide a list "known" builders to contact and their locations.

In Florida,Tim Takash of Belle Isle FL is an experienced, full range chassis fabricator.

Chassis car, 3/4, backhalf, stock body, panel car, composite body? How much finish work can you do yourself? Can you TIG to finish details?

$8-10k and up, way up, depending on the answers to those questions.

$10.00 to $100,000.00

I just got mine done.
It was $8900.00

25.5 certified

And what all was done? Was the car ready to go when you brought it to the chassis shop? Old stuff needed to be cut out? Was the chassis painted, or powder coated?

I was at a chassis shop last week looking at a chrome moly tube chassis build for a S-10. The chassis was bough pre cut with prints for assembly. After it was almost all tig welded together it was time to install the cab. OH $hoot. the main hoop which everything is measured off of is 4" short . At ride height the cab bottom is on the floor. Yes it would be better to buy a already built car that was certified to the spec you want.

Pre-bent and it didn't fit when done? Probably one of those "chassis shops" that said they could do it for $3k and a case of beer. And the plans were wrong, not their problem.

Like other have said if you can find one already done you can save yourself some money. I've done it both ways and hopefully won't have to again. I bought this one as a roller for 11,500.00 with a 6.50 NHRA cert.

You can buy a used car now for 20 cents on the dollar. Maybe a little more for something really nice.

Unless it is a Mopar. Then they seem to want ALL their money in it back out of it more often than not

This mainly applies to Mustangs since there are so many. Anything built off a muscle car type base is more.

What Al. A said is what's happening to me all these guys selling older molars think that they got gold.

It's hard to find a decent deal on any brand tube chassis 4130 car, let alone a mopar body car.

That said, I did find my 70 challenger, 4130, full tube chassis, 4 link, strut car on craigslist in Tucson, az for a real good deal.
So deals can still be found, but I did a LOT of searching before I found it.
