Sounds like the valve train was a bit noisy in the beginning until the lifters got pumped up after it ran a bit. I experienced the same on my LS6 when I changed out the pushrods and valve springs.

we thought it had a misfire, but one of the coil packs Wasn’t connected. Runs good now. He’s gonna use M1 0w30 that I gave him.

71’ C-10 longbed truck. Brother bought in Tennessee out of a barn. We cleaned it up, sandblasted it, repainted it and going back together nicely. The engine in it is 6.0 out of GMC work van also
