I do not know the history of my motor, but I have run into a situation that
I could use a little input on.
It is a Chevrolet 350. I had a noisy valve, and found I could
not adjust the lash on #7 intake. Long story short, I pulled the cam, and
found the lobe to be extremely worn. In my approximation, 1/2 inch. Also
intake on #5 was also worn, almost to the same extent. I bought a new cam,
and have installed it. However, I am still unable to adjust the lash on #7
intake. With the cam and lifters being new, and all the push rods the same
length, that only leaves the valve springs. All the rocker arms arms look
good, and also the studs.
I know there are some good mechanical minds out there. I truly appreciate
any thoughts anyone might have on the situation. Thanks, in advance.
