This engine was not running when it was in a fire. It's a GM crate engine. Was ordered for him to use in a 1960 Chevy. Thinking I'm gunna change out the lifters , push rods, Trunion kit
The inside of the engine when I had it off looked brand new. I'll take pics tomorrow
I'm not sure how that could possibly happen if the bolt is still tight. The stand is what keeps everything in alignment...
If you decide you are going to replace the valve train, I have the components I just removed from mine that I plan to list for sale soon. Lifters, trays, LS3 rockers with trunion upgrades. If you're interested, drop me a PM.
