Re: New Chrysler Engines for S/S
2 parts I have not been able to get info on. The 1-3/4 X 4 throttlebody and the 6.2" long rods. The stock rod is around 6.125. Anyone have any info on the rods or throttlebody?

Re: New Chrysler Engines for S/S
Yes these motors definitely look to be promising. I've heard these things flow over 300 cfm on the intake with no port work. Not to mention how soft the HP rating is for these things. The stock version from 2003 is rated at 345 with less compression and smaller valves. Now they have bigger valves and more compression. Just think how much flow you could get by porting them, and throwing a ported manifold on top. I can't wait see some of you guys build some of these things. I hate to say it, but these motors are part of the new age of Super Stock.

Re: New Chrysler Engines for S/S
I have a Throttle Body for the 360. I think the Hemi T/Bs are available also. The Hemi Heads are in the book with no price or availablity. For ss the stock head might be used. Next time I have a 6.1 or 2009 5.7 down, I will look at the casting # on the head. The T/B is different on the Hemi vs 5.9.

Re: New Chrysler Engines for S/S
Believe the head for both the S/SS Challenger 5.7 and 6.1 is the 369AA head from the 6.1 SRT8 with larger valves. The Manley rod wont work. Has to be 6.200" + or - .025. I don't know of a Mopar rod that is 6.200" so my guess is it is aftermarket or Mopar special built. Since they use Diamond pistons, they might know. The 6.1 SRT-8 crank is a forged piece. Knife edged I am told. I will be picking one up Monday and will know for sure. They will interchange but you have to go with the 6.1 front cover and balancer.

Re: New Chrysler Engines for S/S
Sonny said the throttle body was a 1000 cfm piece. Dang! At 275 hp it will be an easy SS/J car.

Re: New Chrysler Engines for S/S
One thing about it, a 4 hole throttle body is a lot easier to tech than 30-40 year old carb. Are the valves hollow stem like in the factory 6.1 SRT8? Would be nice if Mopar said they were both sodium filled.
