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.
