Machining square fin engines round

The square finned engines from LM-3, Cali-2 do not only have more fin surface for cooling, the studs are also further apart which allows bores up to 92 mm without any further modifications of the housing., including a rocker arm base made of aluminium. Valve sizes up to 47/40 mm were standard, while the round engines had a maximum of 44/37 mm. Of course, we can build a unique round finned engine with bigger bore and valves, but the effort and cost is quite high. And we are far off from using stock parts, making exchange more difficult in case a spare is needed.
So why not make a sqare engine round. We machine the fins of cylinders and heads to a round shape, almost like the old round engins were. But only almost, as we want to preserve a maximum of coolig fin surface. We did not want to copy the round engine, we wanted a more steadfast engine, using as many stock parts as possible, combined with a unique classic style. We supply cnc made adaptors to fit the old round valve covers, either V7 or T3 style covers will complete the modification.

Price is for the machining of 2 cylinders and 2 cylinder heads. Please make sure that all bolts are removed and gasket surfaces are clean.
You can choose wether you want the cylinders and heads glass blasted or not.
