Seems my new hot rod likes to puke coolant out of the overflow tube after driving for more than 30 minutes in the Florida sun

It has a 160* T-Stat and I recently flushed the system out and added an 80/20 mix of water and green plus a bottle of Purple Ice

The temp gauge doesn't get higher than 180*, but she'll piss A LOT of coolant if I let her

Turns out the radiator cap is only rated @ 10lbs.

Went to my local speed shop to get one with a higher rating and all they had were 20-22lbs. caps

I was hoping to get one with a 16lbs. rating since that's what I have on my old T/A, but they said they didn't stock any lower than the ones they had

My question is how do I go about choosing the right cap for my engine?

The dude behind the counter was clueless and said he only deals with imports

I didn't want to chance going too high, so I figured I'd do some research first....
