I don't remember when I got on here last ,but mainly lurk. my question is racing a numbers matching car vs not. So my question is would you ?

If it is a stock build, just for fun sure. If it is built up, I don't know if I would take the chance on hurting it.

Car in question is a stock 75 dart, numbers matching, not perfect but from my research not many we're built. I figure to that even though its not a really desirable car, but then I think to how many have the original drivetrain and low miles on it. less than 100 k, (just for fun )

Numbers matching, emissions legal small block car shouldn't be a damaging combination. Go for it.

A Hemi, convertible E body? Probably not. A 318 Duster or Dart? Sure. It's all relative.

360

Original 340-s, stored the original drivetrain, but small blocks are cheap/easy to find. So it wasn't hard to substitute.

race it. the value on these run of mill cars is going to go down. might as well enjoy them and use them to have some fun. original drivetrain on a 318 car isn't desirable. the only cars really worth any money are the big block and or hemi cars and few 340 cars. everything else is daily driver material

Race it!

Years ago we had the Mopars Unlimited show on in the park on Saturday and then on Sunday the drag strip would host a Mopar day and a decent number of guys would also run their show worthy cars down the track. Hemi and 440 + 340 six pack cars, Superbirds, etc would all be out there. You could tell some guys weren't running them to 6500 rpm, but they still made passes. The guys that own the $$$ cars no longer use them for shows or racing.

The only Mopar guys that are still out there on the track are the A-body guys, and most of them are scruffy street + strip cars that are not worth a ton of money.

I have a relative who has a Formula S Barracuda that he runs Mopar day and maybe one other race per year with and that's it. He has had complete strangers come up to him in the pits and tell him that he should be ashamed for racing with it.

Buy yourself a beater body with good frame and go at it I would personally keep it in 13-14 second range due to cost of building faster and the resulting destruction. My 73 is good example built using a 360 e-58 its reliability is beyond question as I did a basement rebuild and have way over a 1000 runs car was real reliable engine wise and has seen 3 transmissions and 2 rear ends

As I'm an owner of two 1974 Dusters I will tell you this. The 1973 and up Dusters will NEVER be worth as much as the 1970-1972 Dusters and Demons. Have fun with it, enjoy it.
