I have 3 sets of Skip's pumps, 2 on 8BA's and 1 on a 59AB and I am not aware of any instructions telling me not to run stats, just be sure they don't restrict the normal flow,ie, Robertshaw 330 or similar.

I run Skip pumps on my 59AB and do not use thermostats, I usually am only running in the summer. I am sure that either Skip,instructions or GM stated to not use thermostats,but I am probably wrong. I probably welcomed the advice not to use thermostats because of past problems with them. My problems have been with NOS Genuine Ford thermostats that tested fine failing shut and causing overheating and other problems like ruining a brand new set of Edelbrock heads,this years ago on an 8RT engine. Still I agree that Ford engineers knew what they were doing and a steady heat range is best overall for the engines efficiency and durabilty. Some say this brand or that brand restricts and I assume they are referring to new,possibly China made ones. What about the NOS boxed ones that show up at swap meets ,auctions ,Ebay,if they were good enough then why not now? I doubt Ford NOS ones were actually Ford built,probably sourced from one of the many suppliers and Ford boxed. I am always looking for 11A-prefix thermostats,to test .Ebay has one on now,11A-8575-C but the "C" means it is for a non pressure cap and I am using a 4lb cap.The one I am looking for is "B", stated for use with pressure. Anyone know if a specific supplier made these thermostats?
