I am buying a 1984 318 and is it internal or external balanced?
Got the motor today very complete for $300 pulled valve cover
looked clean - turns over - good compression
figured out all 318's are internal balanced - it has an A999 tranny
that will be up for sale what's it worth

The only external balance small block I am aware of is a 360.
 
Internal. Are you getting the trans too? It's most likely a 999.
 
5.2, 318 & forged crank 340 = internal balance
5.9, 360 & cast crank 340 external balance
 
I'm aware of the early balance just didn't know if the 318 changed in later years like a lot of motors did
I'm asking this because I'll be switching it over to a manual

Yes I'll have to check out the trans but I will not be using it switching to 4 speed OD
I figured out the tranny is an A999 and ALL 318's are internal balance thanks
