Which manual and automatic tranmissios came in these?

What rear suspension and rear end housing is being used in these in stock eliminator?

Re: 2009 Challenger 5.9-360/275 Drag Pak
 

Torque Flight or racing manual. Dana 60, 9 inch, not sure of the 8 3/4. A four link. The best answer will come from NHRA in writing.

Rick,

Do you have the head castings for this combination?

Re: 2009 Challenger 5.9-360/275 Drag Pak
 

I do, at this point I'm contemplating a direction to take.

Cool! I know that those things are really hard to find. I wouldn't contemplate that combination unless I had parts in hand.

All of the 2009 dragpaks were shipped with either a tremec 6 speed stick or a 5 speed automatic, most run a 904 or a 727 on the auto front, 4 speed or 5 speed on the stick front. Dana 60 for the rear, maybe 9 inch now since the 11's or so came with 9 inches new.

Search dragpak build manual, and you can confirm at least the tranny info page 29 all info that was presented to nhra. rear suspension is 4 link.

I am on the look for a set of these heads if there are any around available

2009's only came with dummy transmissions that were mostly warranty returns to hold up the engine, and no rear suspension installed . 904'or 727's are acceptable . I've also did a Jerico setup in one. Here's a link to the correct manual that depicts the accepted 4 link rear suspension dimensions and locations . At the time I built one only the Dana and 8 3/4 were accepted . later cars were built with suspension already done and had a "factory 9" installed
I don't know how closely they scrutinize the 4 link these days with minimal tech .T
They had the one I did up in the air and measured the 4 link against the specs in the book.
Here's the link to the P5155775 manual available from Jeg's Pages 34-36 outline the accepted rear suspension.
