I have a 1968 gs400 and 1 of my rockers broke and I would just like to change the rockers & the shafts. Does anyone know of where I can get the whole assembly that is a reliable company? Thanks for the help
I might have what you need. A rocker shaft with all the rockers came with my car along with valve covers that some thought was from a 400 or 430. Lemme dig up that thread with pictures to show you ( I'm on a smart phone right now)
Hi there, here's a picture of the rocker shafts that I have. I don't need them so you can have one of them real cheap if you want. Also pictured are the extra valve covers I have. Now we just need to confirm that the rocker shaft assembly will work on your 400. Can anyone confirm if my rocker shaft assembly will work? Let me know if you need other pictures, look for part numbers, or take measurements.
Kevin's rocker parts will only work on a '70 & up big block that oils through the pushrods. These won't work on a '67-'69 without some more modifications. Devon
Thanks Devon and JR, good info that I didn't know. We'll see what year big block buick he has, and if it's 1969 or older, his search continues.
