What type of radiator cap do I need, I installed a three row rad and want a new cap. How many lbs. etc do I need.

A standard 13 lb cap should work fine. Be sure to have a functional overflow recovery bottle hooked up.

You could consider a 16 lb cap if you live at altitude or if your engine likes to run in the 195-210 range normally...the higher pressure rating will keep the coolant under better control IME...
Try this for interesting reading. It helped me a ton on my 8 second Chevy killer!
