Can a Mopar be built to run up front? If so, what combo would it take? I know alot of money.
Really need to know the Rules and how they are worded, of the Track or series or event you'll be running in. I have had an eye-opener lately at how much the rules actually vary all in the name of the same class. From track to Track and series to series or even event to event.
I have seen stock suspension written as "Bolted to stock location", which means you could use anything that would bolt in. I have also seen it say "Stock Style or Type", if they use that wording you would be stuck with a Torsion Bar front suspension.
That being said:
About your best 2 option for Stock Suspension, (which is the Norm for X275) would be.
1. a-body with cal-tracs and Tubular front suspension and K-frame that bolts into factory locations (If allowed). And Fiberglass everywhere allowed.
2. would be a 1979-1993 Mustang with a Mopar Power plant in it.
One of my co-workers has a 1983 Mustang (Chevy Powered) in this class and he's constantly nagging me to either sell him my motor or scrap my Dakota and get a Mustang to put my motor in.
He is saying X275 it is the same rules on the whole east coast and mid west!!!!!! As also stated in the last x275 thread NO TWIN TURBOS IN X275.
3 different tracks / events 3 different sets of rules all on 275's being the only thing that's the same. Call it 275, 8.5" or X275 fact is not all tracks or events call it the same or run the same rules except that the tire is the same. If you want to stick with the X275 designation then many tracks don't even run that class.
Same goes with Outlaw 10.5 and True 10.5.

http://www.houstonoutlawracing.com/extreme_street_10.5.aspx
http://www.shakedownatetown.com/class_rules.html
That's just 3 that have been pointed out to me recently when I was looking where to put my Dakota Based on how I want to build it.
At Shakedown I could get in any 10.5 class I want as long as I could qualify. At Houston Outlaws I could only get in their ProMod class, some rule in all other 10.5 classes would put me out.
Only one of those events had X275(shakedown) all the others had different classes.If you want to run X275 you have to do it at one of the dozen or so tracks that run their events(MIR,CECIL,ATCO,VALDOSA,PEIDMONT,etc). If you choose to run at tracks that have different rules so be it. You need to pick a class and build your car for that class and not all these different classes you keep bringing up. If you try and build for all these seperate classes your car would probally not be real competive in any.
My point exactly!!! The original poster is in Midland/Odessa Texas. Not many tracks out there and not many in Texas that run X275 or any 275 rules.
It's a haul just to get out of Texas from where he's at.

Thanks for the replies. I would really like to build a new Challenger for the class. Install a Dragpak suspension, large W8 motor then decide NOS or EFI and forced induction. Will run the Texas X275 stuff but build the car to be competitive in Voldasta next year.
2010 Toxic Orange Challenger built by B and B Racecars! All aluminum R4/P5 engine, Proformance TH400 (3 speed) tranny, full Reid case, nodular 9" rearend, full Dragpak suspension, Protorque custom converter, BS3, PTE 85mm turbo, fire core wires, carbon doors, carbon front clip, and a whole lot more!

I would go with the W8 or W9 build before the Gen III Hemi stuff for sure. A 420"+ motor with alot of r and d. Getting the car light will be the trick. I got alot of whats needed to build one. Need to contact a few chassis shops today. I will just buy a new 2011 SE Challenger. They have 0%. Cant beat that.

I agree that a W8/9 turbo engine could compete. I think the GenIII Hemi can as well, just unsure of the blocks holding up and gasket sealing with a lot of manifold pressure. I'd be a little less apprehensive about spending the money on a GenIII Hemi if they had a proven race block like the W8/9 does. I'd probably build a little smaller engine around 400 ci. I really just need to decide whether I really want to spend the money. I'd have to sell a few Harley's, my PS Hemi and possibly some other goodies to finance some of it so it would be a big commitment for me to do it. I really don't want to go into debt if I decide to build it. I have access to a body and have some of the parts as well, just need to take the plunge . If you decide to do it best of luck and keep us posted on your progress!

You need to go to your track mangers and get X275 brought to your local track. I want to get nddra realstreet 275 up here in the northeast.Really like the class and feel its fits my budget much better then X275. Especially now that X275 is a 4.80 class. New record set at 4.78 this weekend, bump was a 5.07 for the class.

I personally think those rules are terrible. SB with an 88mm is at a huge advantage over everything else by those rules. What is the record? ET & MPH?
One day I will have something cool here.
