No factual data to support this but it could be that there was a change of a supplier and drawings werent updated..

So I guess the verdict isn't in yet. This is shaping up to be a good research project!

If 325 had a 3/8 and 375 had a 1/2 inch fitting didn't they both have the same casting number? I have a 3902406 block but it's from a '67 Chevelle.

I can't speak for every configuration or casting Re: Same casting # used for low HP and High HP. But, I do know most engines from the 375 HP years used the same casting, just machined different for the oil fitting and of course 4 bolt mains in the high HP. Same with 427's of '69. It is a 512 casting used in low horse, high horse, and even used both for 427&454. 69 396 block, 272, was used for several HP, even a lowly 2 bbl 265 hp version and, of course the 375 hp all are 272 casting..

Has there been any new info on this? I'm looking for the correct info for my 69 L34 350hp. My understanding is there were two fittings. The first one below is for the 375hp and the second one is the 325 & 350hp. The second pic is of a repop. Can anyone confirm that?

Dave,

Never did get to the bottom of the bushing dilemma. Until something new surfaces or someone can confirm the use of the bushing in '68 L35 cars, I've installed the elbow shown in your bottom photo.

Thanks Bob. According to the AIM and several other pics I've seen, 68-69 are the same for L34 & L35. They are both supposed to use the bushing and the one I posted in the second pic. I'll keep digging for a survivor pic.
