I have replaced the old, dead oil pump with a Melling high volume oil pump. Yes, I now know that the 350 sbc doesn't really like/need a high volume oil pump.
I have also replaced the old cam and double checked the install 4 times now but I'm still hearing the cam moving forwards and backwards. it's a flat tappet cam and I didn't replace the cam bearings because the engine had 20k before I replaced the cam.
My theory is that there's too much oil and the cam is being pushed forward then the tappets and distributor gear push it backwards.
I really like this theory because the solution is inexpensive and pretty easy to accomplish. plus I've got all the tools for that job and I don't have a cam bearing tool.
My question is this: does anyone know if the oil pressure/volume can move the cam shaft around and make the clacking noise?
