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.

Sonny said the throttle body was a 1000 cfm piece. Dang! At 275 hp it will be an easy SS/J car.

All the T/B's are 1000 cfm 1.75 X 1.75 Stock cam in the 6.1 is .590 or so

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.

All three engines have unique features that are different from the OE versions. Check the spec's carefully.
