1952-59 Ford radiator cap

So my new radiator came today and the instructions said to use a 7 to 16lbs cap depending on my motor. so since i still have my flathead should I still run the 7lbs cap or get a different one . and my 7lb cap off the old radiator dont fit anyway Thanks

 

Seven pounds should be good for a flathead. Buy the modern design so you can use a catch can that will **** the overflow back.

 

If you go higher pressure it raises the boiling point,you can probably use a 12-13 pound cap and be OK with the flatty if you do not have an overflow tank,the 16-19 pound caps are for use with the overflow tanks.

 

Thanks I have a beer can for over flow just seemed to be what was laying around HAHA. I should be able to get one at the local auto parts store thanks again

 

I had to go "purty" with mine http://www.skipwhiteperformance.com/detail.aspx?Item=PC-671

 

like the purty, but less filling than the beer can.
