Just found this excellent thread. Water Pumps. I have a 1950 (P20) 218 engine that came from a local hotrod shop- a young guy in Kerman CA who collect and restores 1950 Plymouth Suburbans. He sold me this motor with a Wilcap adapter that will allow it to bolt up to a GM automatic tranny (I'm using a TH 200 4R) He said it was running and driving great when he had it, but the 218 didn't have enough off-the-line power for him. It has the '53 and later internal bypass thermostat, and straight neck and it looks just like JB Neal's pictures , including a newer NAPA water pump. Am I understanding correctly that even though the new NAPA water pump will work with both pre and post '52 block designs, using the internal type on the older external blocks will lead to warmup and/or operational problems?

Solving unusual little problems with my '51 B3B is a saga for the ages. The latest has to do with the thermostat housing. On one hand, the correct housing for the '48 - '50 trucks has all the proper dimensions to fit my '51 properly, except it has a water bypass tube which is incorrect for my '51 (which has the internal bypass). On the other hand, I bought a brand new housing (the one on the right) that was supposed to be the answer, but it isn't for two reasons: Reason Number One: The new one doesn't point at the radiator and it causes a solid hose to kink badly. I've tried. Reason Number Two: Even worse, the outlet on the new housing is 1/8 inch wider than it should be. It does not match the radiator inlet. Both should have a 1.75 inch outside diameter. I've searched the internet for a part that looks like it will fit correctly but I have come up empty. So, unless someone on the forum has discovered the perfect solution, I'm going to have to fabricate a housing from scratch that actually fits properly including a tube that points in the right direction. I just wonder where all the original housings have gone. I've never even seen one.
