Hi guys, OK don't laugh. I am learning how to work on my 1974-75. 455 Olds in my flat bottom. Husband passed from cancer last Dec & I feel like he would be proud. The thing was spewing oil everywhere. Used to be turn key. With the help of my neighbor I tore it all the way down with heads off. All new gaskets, new headers, bilge pump & switch. I bent water lines installed a puke tank. Found a guy from Craig's list to fabricate a plate for me. Put back together & she purrs like a kitten. Had her up to 3500 rpm running great then started hearing ROD KNOCKING...Shut motor off immediately! I started it back up for a split second to see if froze. Nope it started. Didn't go thru. So before I take valve cover off in looking for tips & pointers to fix it myself.
Do I need to do both sides?
Its was just the drivers side.
Do I replace all rods & rockers?
Or just one rod?
What's the specs on tightening?
I have a million questions & am excited to learn.
Please help...
