Fire away Peter......

Is this 216 the original engine....

Is the pump a 216 in the block water pump or did you use a hybrid set up with an adapter plate

Why do you havea throttle set up like a Cab 11 CMP....? never seen that before....



My 261 has a hybrid 216 water pump and was strongly recommended by other engine builders to insure that a short by pass tube be used and NOT to plug the threaded outlets with pipe plugs....... Like you..... I ran a rubber hose for a while but did not like the stress in the rubber tube so I made a solid bypass with regular 1/2 inch house soldered copper pipe.......

Does you engine have a steam line running from the rear temp hole in the engine head to the elbow of the radiator

Do you have a modern mechanical temperarture gauge that you can connect to the engine or relying on the original CMP gauge

What temperature thermostat are you using

I have pictures that I can share.......

Over to you.....
