Slant six to small block 340-360 engine won't fit.

I wish i had gone one piece.. getting the rubber ends to stay in place was a pain in the balls on mine
You should try to get the timing cover back in place after a chain and gear R&R. In the vehicle. Silicone saved the day. It wasn't pretty but it didn't leak. It was a V6 in a 4wd. Dakota. I didn't want to pull the pan.
