When people rattle off things like 440 Hemi, like there is no such thing,they are wrong, Stage V built 440 Hemi engines, before Mopar Performance reissued Hemi engine blocks. When people say that Hemi Sixpack engines don't exist, they are wrong, Tom Hoover had a few prototype Hemi Sixpack intake manifolds made and toyed with the idea of running the setup on the Hemi, those setups were the inspiration for the Hemi Sixpack /Six Barrel setups my friend runs on his 71 Wingcars. When people say things like 340 Hemi,like it dosen't exist, well they are wrong again, Hot Heads made Hemi heads for the LA engines, so that is possible too. And as far as Charger convertibles go I built two of them,and there are others out there. Richard Sias the lead designer of the second generation Charger, was building a Charger convertible too.
