Are they new eagle heads or a 6.1 head, or what? What pistons are used in a stock drag pack? Diamond? JE? Do they come with a solid or hydraulic roller? If solid what rocker gear? Would a 96 dakota with a 5.7 hemi be able to fit in SS/TA or GT class? thanks in advance...Justin Interested in having you car wired? Drag car, street car, EFI swap? PM for details

Would a 96 dakota with a 5.7 hemi be able to fit in SS/TA or GT class? thanks in advance...Justin I don't much about the specifics of the engine but I can tell you that these engines are legal for the TA and GT truck classes. With the minimum weight in TA I would think this engine would be better suited for TB which is a SB only designation if my memory serves me right. The downside to TA and TB is that they are carb only classes. TA mandates an 850cfm carb and TB mandates a 750cfm carb and both classes have an 8.5lbs per cube weight factor. I forget what the minimum weights are but other than the carbs, you can pretty much run whatever else you want. No rotating assembly restraints or head restraints but you will have to kick some rpms and make some good power in these classes to run well as the current standard for both of those is 9.00 and faster for the most part(at least 9.20's). In the GT truck classes you would run the engine according to stock specs within NHRA guidelines except that you aren't limited in vavletrain or intake manifold. You will however have certain restrictions to maintain. C.R., a certain port volume, stock sized valves, standard efi system, spec rods, and spec pistons, all of which have to mach certain specs and weight. It sounds more technical than it is but those are just some of things you have to face in putting together the engine. On the bright side of things though, the GT HP ratings for the 5.7 and 6.1 are untouched and both ratings are softer than a brownie, especially the 5.7. 305 HP rating would put you on the minimum weight for most of the class designations. You could probably run GT/TC or TD and still run on the minimum weight. Its definitely got some potential and wish you nothing but blessing going forward. I personally hope you decide to run TA as I would like to see what these engine could do when transformed into a high winding rpm all out modified style engine.

wldtm OP super stock W Joined: May 2005 Posts: 1,130 Dayton, Ohio	Thanks for an informative post. I think I like the idea of the GT class for now. I personally like the 5.7 for the hp factor. So lets say the 5.7 gets factored because of a drag pack car blows away the index (as we have seen in the past). This will then raise the factor for my engine in GT too? Correct? thanks again for the input...justin Interested in having you car wired? Drag car, street car, EFI swap? PM for details

I have been told by NHRA that if an engine has fresh air (scoop) in its normal class then it has to be used in a fresh air car in GT. The opposite is also true, a non fresh air car can't be used in a fresh air car. So the Drag Pak engines in GT has to be in a scooped car such as a 68 hemi Cuda or Dart. Since the rule book says that the GT truck class has the same rules as the GT car rules with the exceptions listed in the GT truck section it would look like the Drag Pak is not legal in a truck. Don't know of any truck with fresh air. I'm using a 68 AH type Cuda. As for the 5.7 and 6.1 engine, the 2009 engines both came with the 6.1 SRT8 heads with slightly larger valves, casting#5037369AA. 2.10 and 1.60 valves. The pistons are 12.7-1 Diamond #46191. Has a hyd roller with .584 and .552 lift. Non adjustable rockers. I haven't started my engine yet. Have had some shocks on parts. Jesel drop in roller lifters for $3200 and rockers for $4800. Harland Sharp does have a set of rockers for $1800 that are adjustable. Think the rods are Scat with ARP bolts. Manley and K1 make approved rods. As for the HP factors, the SS and GT factors are seperate so it would take a GT car to hit the GT factor, not a SS car. Good luck with whatever direction you go.

If you look at the classification guide you will see that the GT factors are separate from the other SS categories so until you or someone with your combo in GT bust up the index, you don't have to worry. I think the 360 has been hit a couple times as Mark Nowicki in the Northeast upgraded his 360 to the dragpak version and has been loving it. The stock cars are the only ones having factoring trouble right now any way. No Super Stock DragPaks have been to the track yet. MR2Performance built a couple of Super Stock versions and one of those cars is teamed with Rock Haas and they have been doing to some engine development but it has yet to hit the track. I think their searching for more ways to make power. Adriel Paradise Substation Design Engineer III

Don't know of any truck with fresh air. I'm using a 68 AH type Cuda. Do some more research. Neither Mark Nowicki and his Avenger nor the '70 Duster that is run out of the Teuton stable have fresh air scoops. They both have the 5.9 Magnum Drag Pak engines in SS/GT. I know of other non-air combos being built also.

Their dedication to this engine program and this entire Super Stock Challenger Project while I am on the road working is unsurpassed. " In Case Your Wondering" They know what it means. Thanks Guys

Mr. Mike, I've been waiting to see what this car can do for while and the hard work that you guys have done is very impressive. Look forward to seeing it at the track and hopefully, you guys can make it to Belle Rose(my fingers are crossed lol). And in regards to the cost, we all know the exact number, we just remain in denial to make ourselves fill better. But at the end of the day its about having fun and learning knew things. You never stop learning lol. PS: I pray nothing but many blessings over the project going forward. Adriel Paradise Substation Design Engineer III
