[QUOTE="atafonso, post: 596176, member: 23592"] With a stock cam and stock valve sizes you should not primarily be concerned with power figures, what it will make if the displacement is increased it's way more torque starting at very low rpm's. With the stock cam the engine can rev more than 4-4200 rpm but the power curve will drop rapidly, so no sense in revving higher, therefore restriction will not be a great issue unless you plan on running the engine constantly above the optimum cooling range of 3200-3500 rpm. I would convert to a doghouse cooling at least and monitor closely the oil temps but surely it will need extra cooling if pushed hard uphils with a heavy Bus. Using a single carb, max i personally would go is 1955cc. It will be a tractor😉 Abel Ps: Keep the mag case, alu will run much hotter. [/QUOTE]
