It seems my rocker shafts were installed backwards! Possibly when the engine was rebuilt in 2010.
I purchased my 71 Duster in 2017. New to Mopar's & learning. I have driven and worked on it since then approx 22k miles.
It was rebuilt in 2010 71 318la, bored .030 over, stock heads, comp cams Thumper camshaft, pushrods, springs. 340 intake, and a holley.
In 2021, I upgraded the top end w/ xheads, weiand stealth intake, a 650 proform carb. kept the pushrods and internals the same.
I disassembled and put it back together exact by pics and labeling everything.
I had a bit of timing chain strectch (approx. 12 degrees) develop because I drive the heck out of it!
I have torn into it and watched videos, explored forums to do the timing chain and double check internals with a scope. cleaning things up. etc.
I came across the rocker shaft discussion and mine are installed backwards.
So do I run them the way they have been?? Or take the shafts apart and install them correctly notched in the correct direction?
Its easy to do now and, I want to do it correctly!
Thanks for the input.
