There would definitely be a lot of engineering required, as both the engine & the trans are computer controlled. That means sensors, wiring harnesses, computers, etc would have to be provided for as LB says. I dont know if this engine has been officially classified as a sb or bb, but it is pretty large externally, though maybe not quite as expansive as the old hemis. It does not have flat top pistons. I havent torn one down, but I have read tech articles on it, & while the pistons are not quite as high domed as the old hemis, they are still raised to fit the combustion chamber, otherwise compression would be very low. There has been a car or 2 in the mags w/ the new eng, so it can be done. The very early hemis were built as small as 241 ci, but it was still a very bb externally. Ovmf
