im looking to purchase new stainless steel hoses for my motor and im wondering what size they are?

i measured with a measuring tape and the left heater hose going into the firewall looks to be 0.8(im assuming its 0.75 or 3/4) and the right heater hose looks to be 1.1 or 1.2, which equals to what 5/8's?

and the radiator hoses looks to be 2" in diameter, is this right?

thanks for any help

i was just looking for hoses on summitracing.com

 

i dont think it makes a difference does it, but the motor is from an early pickup

3970010 is the block number (69-80 350 4 bolt)

but the hoses comes off the radiator and from the firewall so it shouldnt make a difference

 

They typically go by ID, and are 5/8" and 3/4" for the heater hoses.

I've never had occasion to check the radiator hoses.

 

thanks very much
