In the old days, we're talking 60's thru 70's here. Nitro marine engines as we know them today were still being developed, and it was common to use airplane engines with a cooling clamp around the head. Not so today. Hardly anyone uses plane engines or any aircooled engine larger than a .12 that I know of. Unless your trying for a retro look...
Theres a good selection of affordable marine engines out there. That Novarossi thats mentioned before is one of the hottest engines out there now and would smoke that dynamite .32 you had...</span></span></span>
