Crate Engine
The 390 in my '67 bent a pushrod shortly after installing this used engine. I have to check the timing chain. Any chance if the timing chain went the engine could still be serviceable when fixed? If not anyone had good luck with crate engines? If so from where?

If you buy a crate engine from any internet reference you assured of getting something with a top-quality Shanghai rattle-can paint job on something. You bust your **** to R and R the thing to learn the hard way. Like on teardown.
There is no cheap way to rebuild these old motors. Good labor gets paid a wage to keep them living happily in the local environment. If you want to get a good rebuild, ask around town. Find the best guy. Cheap prices get you cheap parts with a high school cluck running the boring bar. Take the engine in and insist on seeing the box for the rebuild parts and the gasket set. I have even been in shops where I watch the crank dropped into a properly installed rear seal. I have knowledge, but a rotten spine.

390? Used engine? How did you know it was a 390? Did you stroke test it to begin with? Is it a case of "390 on sale day, 352-360 any other day"?

2000-3000 I am really looking for a stock rebuild that can run on unleaded gas. I've had the truck for 18 years, and I am trying to finish, up the projects swapped out an old engine that had no compression with one from an rv with good then a pushrods went a couple of days after install and working through old gas.

Hydraulic lifter preload is generally .020-.050, not enough to bend a pushrod. What usually happens is the valve gets hung up in the guide and the lifter tries to open a valve that won't move. The weakest link is the pushrod.

I guess I was wondering if a national auto parts chain with a warranty is an okay to do. I don't know much about engines, I'm just trying to get this truck as a daily driver in the summer. I have had it garaged 18 years

It is neither the cam nor the timing chain.
