Pretty cool "off the wall" engine. As for the aluminum MEL heads, I imagine the market would not be huge, but perhaps if the heads were available, there could be some added incentive for MEL powered nostalgia cars. A local bracket racer runs a 58 Olds Super 88, all "old school", 371 cube Olds , 4 speed Hydramatic etc. Over the past several seasons, he has gone from mid 15 second ETs, and normally runs 13.4-13.5s, pretty impressive for such a heavy scow. He used to run an Offenhauser low rise 2x 4 barrel setup, but has since installed a factory Olds J-2 Tri power setup, but one thing that really picked him up was a set of aluminum cylinder heads. (Yes, Really!, For a 371-394 Oldsmobile engine.) I asked where he found the heads, and he told me a group of nostalgia racers got together to have some heads made up for their Olds powered gassers and gas dragsters. I don`t know how many sets they had cast, but I doubt that it was a whole bunch.
