Boy do I feel silly. I was expecting worse case scenario with that loud knock and burning oil so badly. Went to the shop today finally and pulled the valve cover. One of the rocker studs had backed out quite a bit. So we tightened the stud down and it's running like a champ. Hopefully get a few more miles out of her after all. So the 250 inline six is staying in for a while and I'm keeping the 71 Camaro 350 in the Chevelle for now. Going to try to get the Chevelle back on the road soon too.
I guess I just wasn't prepared for all the crazy horsepower a Chevy inline six makes. So powerful it just throws internal parts everywhere! What a beast
