Looking to find out the most correct pcv rubber hose to use on a March built '66 Shelby. For example, is it ribbed or alligator finish and what approximate outside diameter is it? According to what I have seen in pictures here and what I have read here, there could be a difference in hoses on the engines assembled at Ford with the hose attached and those cars where the hose was installed at SAI.
Thank you.

There was no reason for SA to install the hose given it already came on the 289 hipo.

+1 Agree no reason for Shelby to mess with something like that and they didn't.
Like the heater hoses the hoses were ribbed to identify the supplier for quality control purposes
Couple of originals to illustrate. Notice that they are the same maker/provider. This is what I've typically found on 66 San Jose Mustangs and Shelbys used for this purpose Hipo and non-Hipo

I don't think it is absolute one way or the other as it pertains to ribbed hose or not. I have also seen smooth hose in what appeared to be unmolested context.

Are of the same opinion on other small dia hoses like heater hoses and 67 breather hoses?
So with all that said, which would be a correct style hose for a October 1965 built San Jose 66 K code/gt350?
Any recommendations on where to purchase a correct reproduction or NOS hose along with the correct clamps?
Thanks, Karl

No difference based on when during the production year IMHO. As for ribs no ribs your going to have to make the choice yourself - with all that said - Bob and I have posted our opinions at this time

More like breather hose but seem to be a molded shape. At least the ones I have taken off retain the contoured shape.
Hi Karl,
Brant at Virginia Classic Mustang sells a ribbed hose for the HiPo oil cap to air cleaner. See link:
https://www.virginiaclassicmustang.com/65-66-GT350-MUSTANG-OIL-CAP-TO-AIR-CLEANER-BASE-HOSE-WITH-CLAMPS-P399360.aspx
They also sell a PCV hose that could be cut for the GT350 application. IIRC, you only need one bend for GT350. See link for image. Not quite an exact match.

See link for OEM hose. You will have to scroll down some.

"My" opinion from personal observation is the original PCV hose was the original Ford hose cut to fit the new location. Part of my opinion is based on the fact that "originals" vary in length , and the shortened end is often a bit jagged as if cut by a razor blade. I welcome other opinions.
