Hi there,

I would like to know what size radiator cap should I use on my cobra,

I'm running a 351 supercharged with an electric water pump, should I use a 7 or 14 or something higher ?

Thanks

Nick

Nick, I'm using a std. 15# cap on my T-filler. On the radiator I'm using a Moroso 25# cap that I have sealed the vacuum relief valve with epoxy. I have a 347 stroker,10.5 c/r,EFI with Trick-Flow top end. Good luck, Randy Richards

Pay particular attention to that statement. It's the important part id you want a trouble free system.
