Mopar GT combo?
 

A new racer-to-be in my area has asked me (believe or not) to gather info for his new Challenger. It's a body-in-white deal and he's gonna' run SS/GT. Now, I'm pretty familiar with the older Ford HP ratings in relation to best "rated" combo's to look at, but I don't have a clue about Mopar's. He wants to run a big block 383 - 440. So what's all you Mopar racers ideas? Year, body, etc.

Re: Mopar GT combo?
 

At the risk of leading someone down an unethical and immoral road he might consider one of the 3 Drag Pac engines. Sorry, couldn't resist. He could run regular SS or GT. If he chooses a 383-440 it will have to have come with fresh/ram air since the Drag Pac has a scoop. If he wants to stay away from the FI and run a carb, I would try the 70 383 from the E-body. It was available with the shaker so it can run under the Drag Pac scoop.

To use the body in white Drag Pak with scoop he can run the following: 1964 Max wedge, 1965 race Hemi, 1968 race Hemi, 1970 340/383/440/440-6/Hemi.....all of these combinations could be had with some type of hood scoop during their day.. Guys, correct me if I'm off on this.

If he does not use a hood scoop then any mopar motor will do. To see where it fit he would have to look at the classification guide and weigh HP to weight ratios.

I'm partial to the slant six/4 speed combo myself......lol!

a "New Challenger" Body in white ? Id love to know how hes pulling that off, I and several others have tried, hell Mopar Perf, couldnt even get them for the DP Program.

Drop me a PM and lemme know.....

But Stewart is right, I would look at either the 5.7 , or (and I cant beleive Im saying this) but the 5.9 After Jeff Teutons success, knowing he has forgotten more about motors and the LA in particular than Ill ever know, but I never ever would have guessed it that fast....if its as fast as I think it is.

5.7's blocks are cheap and plentiful the heads for the 5.7 Dp and 6.1 flow over 300 CFM in 225 ex.....The heads are off the shelf items if you want to do your own and can be regulary picked up on ebay, the parts to build one are CHEAP, like 299 for rods, 349 crank, 5.7 block 1200 if you get a whole short block. Less if you Craigslist it, a 5.7 can TAKE a .075 overbore on most blocks easily. Heads used 1000 set, + setup another 1000, , cam 500, timing setup 100, rockers and shafts 40 ea (x4), Ross will have pistons at about 850 a set soon (Diamonds are 1050) Pan 500, Oil Pump 40-100 depending, the manifold and tb are the killer at about 2k....

Im building my 72 Chally to use DP running gear, but it will be done so it can run Stock, SS, and SS/GT .... a "Convertible" as it were, Im ordering cage tommorow.

I am dying to know how he thinks (or has) a BIW ? Unless its from a salvage car and not a "BIW" direct from Ma Mopar....

There was one body in white offered by Mopar that I know of. It was pulled from the line for some reason but couldn't be used in the drag pac program since it had a moon roof so it was sold thru an offer on Moparts a little over a year ago. Zippy was the one who listed it.

Re: Mopar GT combo?
 

What about the '62 383 combo that Bennett runs? If I'm reading it right, it's 330 HP in SS/GT.

Re: Mopar GT combo?
 

How about a single 4bbl NASCAR Hemi? I didn't even look but it may have the original HP rating and not the Stock factor.

Re: Mopar GT combo?
 

A question was asked not long ago on Moparts about this BIW and it was reported that it had been sold... Don't know who or when but that was the reply.. Maybe he bought it???

Re: Mopar GT combo?
 

The only place i see a challenger would work would be base super stock. no gt or modified. Think of the aero advantage a daytona,avenger,or stratus would have.
It would take a lot to overcome this. Any of the engine combo that come in a drag pac
are real good. I will have a 5.9 on dyno in 60 days.

Re: Mopar GT combo?
 

5.7 DP Engine, only difference between it and the 6.1 is the bore. But the factors between the two engines is much different and more favorable for the 5.7. The 5.9 would be an excellent choice as well and would be the cheapest option I'm sure.

305 HP factor

If you plan on running the car at around 3100lbs, GT/DA would be a perfect fit for this combo.

I would like to put to put a 5.7 DP Engine in a 96 Neon coupe and run GT/AA at the minimum weight (2600lbs) if its possible. I figure if they can get a Fox Body mustang to 2200lbs, then I could get a neon somewhere close.


Hey guys correct me if I'm wrong but doesn't the hood scoop refer to the body style used, not the engine combination. Thats my understanding from reading my rulebook(09).
