361 engine specs

Your English looks pretty good to me and welcome aboard!

As far as specs go? What specs are you looking for? Torque specs? You can follow the other B series engines without issue. Your biggest challenge is pistons which can be found at Egge machine .com. They will be cast aluminum pistons.

Next would be the small valves if you need them. Otherwise, it is the same as the other B series engines.

These engines also made there way into cars. There not solely a truck engine. Here in the USA you can find them in a old Charger. It was the first option box upgrade over the Poly 318 in 1966.
