With due respect George, and I mean that most sincerely because I have learned volumes from your posts and Facebook Cleveland page, let's discuss the needs of the AVERAGE Pantera driver and the resources for quality replacement parts that are available NOW.

I have run the Stant #29468 uphill on the Ortega Highway on a 98 degree day, with modern sucker fans with no heating problems whatsoever. Lets move on.

This Flowcooler thermostat has become a talisman for Cleveland enthusiasts, but lets talk facts and data on what is available NOW. The 333 is not available. For someone who is bolting a motor together tomorrow, and needs resources that available now, then buy the #29468.
Here is why you really should consider the Robertshaw / Flowcooler thermostat.

Notwithstanding it's warm-up benefits due to the "button" that engages the bypass restrictor plate in the block..... Note the much larger opening vs. a "standard" design unit. The standard one came out of my old motor.
