Need measurements on late production Olds S-23
Posted: Sat Jun 17, 2017 8:11 pm
I've just discovered (to my disappointment) the attachment tubing on a late production Olds S-20 is smaller than that on my LA-era double-rotor horns. Now I'm curious as what size tubing was used on late production S-23's. Anyone out there have a late S-23 they can take some measurements on?
(by "late production", I mean the version with the valve springs inside the valve casing, under the bearing cap)
