I found these the other day and took em home with me but I have no idea what they are off of. Anybody recognize what these go on? Looks like it says "GM 348222" on it.
Yea, I just searched ebay and they are the same as some guy selling 80s 350 manifolds. Shows what I know about new trucks, I thought 350s all had the rams horns on em. I've never had a truck newer than 72 though.
Number looks to be 346222 to me. If that is correct, According to what I can find they were used on 307/350/400 Small Blocks starting in 1973 and used until 1980 on the Chevelle/El Camino/Caprice/Camaro/Monte Carlo http://www.nastyz28.com/sbcmenu.php
I had some like that on a Camaro engine.Think it was about 1977 but that was too long ago for me to remember.
