Is 20W-50 too heavy for my 340?

So This is my take away from asking if 20W is to heavy for my 340.

1. The question is application specific.
2. It depends upon the bearing clearances which is a function of engine set up and wear (mileage).
3. Depends upon ambient and operating temperatures.
4. Depends to a small degree on how you drive and what your looking for.
5. Depends upon what your oil pressure is and what you’re currently using (oil weight).

If I left anything major out above feel free to add it.

BUT in general 20W-50 is commonly being used in the 70’s small block Mopars and I am sure in 327’s and many other engines across the board.

In my case it’s probably what I used to run and what I had in the shop. I have it now in my car and when I am up to the task in getting it running will assess the oil pressure and go from there.

Thanks for all your comments and suggestions guys!

How is it for ZDDP content? I'm assuming you're running a flat tappet camshaft?
