Yes they are good engines. some near the end of production had way different tolerances though. timing was way different on the same size engines. Webra 36's with a bit of work kind like CP did would turn 8x7 at 21,500 or more. The Webra 55 is a great little engine also. If they do start making them I think the 145 would be an awesome engine as it has a big stroke and has same size bore, meaning its a square engine.
