You almost never get a dist to fall back in after lifting out. As you lift it up the cut of the gear rotates the dist which turns the oil pump drive and then it doesn’t line up going back in without rotating the engine. I think you’re a tooth off which will work if you can turn the dist that much. I would reset it.

you need to turn the oil pump drive w/ a long flat headed screw driver.then the distributor will drop in,if its still off,turn it a little more and try again.hope your on the #1 compression stroke and not #6.

I have Never dropped a dist back in a chrvy V8 without having to turn oil pump rod a hair back to get dist back in same place. Use a big long flat blade screwdriver.

Looking at your picture compared to mine(502 mag) you are off a tooth. The 2 electrical connectors I thing face almost straight back toward the transom. I definitely remember the cap hold down screw ends up almost under the intake plenum and difficult to get too.
