Hello guys,
I had quite a bad luck with my ‘cuda last week. When cruising on the highway suddenly there was a noise from under the hood and the engine started to work strangely.
On idle it seemed like more than one cylinder was missing. I could find out that number 6 and number 8 were not firing (spark was coming). Yesterday I removed the valve covers and found a pushrod of #6 broken in two pieces and the rod of #8 could be pushed back without any effort. After further disassembly I could see that there quite obviously is some damage to the lifters and the camshaft itself at least for those two cylinders. I still need to find out if #6 and #8 is the only damaged area.
However it looks like at least the camshaft, the lifters and the pushrods need to be replaced. And I still don’t understand the root cause of that damage.
Unfortunately I don’t have any information on the rocker arms in my car. It’s quite obviously not stock. Do you have an idea how I can find out what is installed now? I guess I will need this information to set up the new cam shaft and pushrods correctly. Or is it possible to match the rods and lifters without knowing the exact brand and model of the rockets?
I know that the pushrods came from Smith Bros. :
NR34A-CB 3/8 x 0.049 4130 non HT, no oil
C51964A 5/32 R Cup
B51964SA 5/32 R Ball
I have found an invoice on those. But so far, nothing on the rockers. Does anyone know that company? Any comments on them? Does it make sense to order the pushrods from them again?
The camshaft was the Edelbrock Performer-Plus Mopar PN 2192.
I hope you have some ideas to share.
Thanks!
