Mileage on the engine is 48,000. The stock cam has about 35,000 miles (previous owner had a TR224 cam in it for a while). It does have isky 295 springs, which are pretty stiff. I think it's lack of oil. The previous owner said one time after a dyno run the oil pressure dropped to basically 0. He shut her off right away, but I think thats what caused this cam issue (and probably my cylinder scuffing
Anyway, a new ported oil pump is going in with the new cam and lifters.
