I was wondering how much the pressure cap should be on the Header Bottle?
I have the Stainless Steel Bottle and it has a 16lbs Cap on it.
Is that ok?

I think the stock cap was 15lbs. 16lbs should be okay.

15lbs are easily found and not too pricey:

Yep - stock/OEM is a 15lb cap. 16lb should be fine.

I have seen a pic a while ago of a cap that actually had a pressure gauge on it. Anyone have one of those and if it's worth having?

You mean one of these? http://www.amazon.com/Mr-Gasket-2471SDomestic-ThermoCap-PSI-SLVR/dp/B000OF9LRO

I've seen them on DeLoreans before, but I have no experience with Mr Gasket products, so I don't know if they're worth the money. It sure looks handy, though!

P.S. - It's a temp gauge, not a pressure gauge.

I thought it was a pressure gauge, you could be right Farrar!

I don't see why a pressure gauge couldn't work on such a cap, but can't say that I've ever actually seen one...

Mr. Gasket was a quality name brand in the 80's when I was hot rodding my 1969 Camaro convertible and my 1977 Pontiac Grand Prix with the Buick 455 big block in it. Man that Grand Prix was dangerously fast! It had a quadra jet carb with vacuum secondaries and I would feather the pedal to make sure the secondaries were gonna kick in , put the B&M shifter to second (automatic turbo 400 tranny with shift kit) then down to first and as the car reared back into first I'd nail the gas and go down the street sideways smoking the tires. People were actually scared to race me. Those were the days!
