An ex father-in-law of mine had an early (68-69) LA 318 hooked to his sawmill. He and two of his other sons-in-law ran that thing until he finally sold it with the property it was on in 2005. He got it when he bought the land it was on in appx (70-71). There is no telling how many hours it turned a 48" sawblade to rough cut timber he and the two boys felled and rough cut timber year round.
