OK, can't beat a 0-360A4M in a 172H - THAT is something! But it's a rare bird.
Or look for a T-41B Mescalero, or a French 172 Rocket, both with the same 210HP IO-360 H, or go even further with the 400HP conversion V8 Corvette engine from Quietaviation (C172 India N46240, does anybody know how many Experimental V8's are out there? Price was very reasonable.) - even runs on AutoFuel ... These will all be more like a little shrunk 182 and less 172ish.
