Torque Monster !

I’m not recommending to do this, but as this is basically a thought experiment. You’d probably be better off going the other way. Do like how car manufacturers are doing it now.
Small displacement and turbo, small efficient bore high cr and longish stroke.

eg.. 273 with a 360 crank for about 300 cid. 302 heads mild ported and with quench plus higher rocker ratio like 1.6 or 1.7 with moderate lift roller cam and really short duration. Add magnum beer barrel intake with a small turbo and inter cooler that works over 2000-4000 rpm range to give passing power and help off the lights in a intersection. Try to get CR in the 9 - 10 to. 1 range, with the help of thermal coatings and do everything to lower ambient air temps, add water / methanol injection etc... plus OD for 1700-2000 rpm crusin. Cost a bundle but probably be an efficient package.
