I was pondering buying a 65 dart GT and thinking through what could be done with it and thought a FAST car would be unique, obviously not the fastest ever but a 4 inch stroke crank could put it up to around 340 inches depending on final bore, could even go close to 360 with a 4.25 stroke and honda rod journals. Heads could be made to flow enough for 400 hp. It would be a pretty light car with a short-ish wheel base so mabey it could be made to be respectable. What do you guys think?

I've seen an early A pick up 1/2 sec and 5mph in the 1/8 by just swapping to a set of small headers. This was on a street 360 with stock heads, hyd cam and dual plane, nothing crazy where it would "need" a set of headers, that 90* bend and crimp in the manifold on the dr side kills it.

You know that by the rules you are allowed to use any block of that family?? So start with a 340/360 block and put 400+ cubes in it. You can upgrade to a 6" wide wheel and upgrade to a G series tire of the same section as stock. I think my car should have 14x5.5's with E7014's. I'm running 14x6 rallyes and G70's. As for the exhaust, sure headers are going to be better but its a moot point. I am not sure there is a huge difference between "good" small block manifolds and "blah" small block manifolds in the grand scheme of things. I agree with Tom, do it. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"

It's all about doing the BEST you can with the entry you choose to bring. Not too long ago they said a FAST six pack big block wedge would never be able to make it into the elevens. MB

Also would it be limited to a single exhaust? I had a 360 in a 66 dart 4dr with 302 heads 273 manifolds and it ran a best of 9.43 in the 1/8th with a one leg 7.25 2.94 rear. Could I run an 8.75 or 8.25, I think they only came with 7.25s in 65? I am not causing global warming, I am just trying to hold off a impending Ice Age!

As for exhaust, thats a good question. The class is for high performance cars with a minimum of a 4 bbl carb and dual exhaust... Thats a question for the FAST tech guys. You can run any axle offered by that manufacturer. Same goes for transmissions as long as its no more than 3 speeds for auto or 4 speed for stick. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"

Mabey the 7.25 could be made to survive with enough weight removal from the car and the puny tires. Any one make a spool or aftermarket axels? The weight saveings of the 7.25 could be an advantage it self. I am not causing global warming, I am just trying to hold off a impending Ice Age!

There was an SG unit and 4.10 gears on there a few weeks ago. With small street tires a 7.25 w/SG would hold up for a while. "Everybody funny, now you funny too."

I made about 50 1/8th passes on my old 66 dart with a 7.25 and finaly broke the spiders drifting through an intersection WOT Mabey I could get someone with a lathe to turn out a locker? What about axels? Shot peen, cryo treat and hope for the best? I am not causing global warming, I am just trying to hold off a impending Ice Age!

You can use ANY solid axle that ever came in a mopar, or a stock appearing aftermarket version. http://www.fastraces.org/ I hope you build it, I think it would be a cool combo, and you would have alot of fun with it!

The manifolds are the killer. Why not try NHRA stock class? I believe that you'll find that you can run headers and any size tire that will fit the wheel well. With a 2bbl 273 and a 904, you may fit right into U/SA.

And the FAST rules are pretty concise easy to understand. I'd suggest going thru them a few times as I think you'll find most answers there. The forums are a great place for more input too. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"
