What this means is that you will be able to run the SRT6 motor with the NA coupe's 6 speed transmission. I have considered doing a build on my car for the 2009 season if things go well this season.

What the build would consist of would be the swapping in of an SRT6 motor or atleast installing all the parts on my NA motor that would make it an SRT6 motor. I don't know what parts are different on the engine internally or externally other than the supercharger itself and obviously the intake manifold. I would also install a set of coil-overs (probably custom Ground Control units). The big questions I am putting out there to everyone is are there any limited slip differentials on the market for our cars? Another thing I have no clue on would be heavy duty clutches and lightweight flywheel availability or would these all be custom pieces as well?

For tires I can fit what ever I need on the rear without touching the fenders so that is easy but the front fenders would probably need to be rolled and flared to fit a 285 on a 10 inch wide wheel with the proper offset to clear the control arm. Bryan's (Nocones) car weighed in at about 2,893 lbs at race weight in Kansas this year. I figure you could drop a bunch of weight in things such as putting in race seats, removing radio and speakers (wiring must stay according to the rules) and at the extreme dropping the air conditioning as well. You would be gaining weight when you add the supercharger system though. HDDP how much heavier is the SRT6 motor over the NA motor since you are doing a swap or are you not sure?

This is all just bench racing in the off season but I am curious as to what we can come up with for ideas.
