HELLLPPPP! engine coding amongst other things.
I have what I thought was an 84 1piece rms 350 from a 3500 series van. block code UFC when I took the heads off today though I found this. The bore is clearly not 4 inches I know the picture is bad but I only have two hands.
also have a casting code from the back of the block which I assume says 14094766. can someone please help me understand this.

Re: HELLLPPPP! engine coding amongst other things.
How come the front id number suffix would be UFC?

Re: HELLLPPPP! engine coding amongst other things.
The later model engines will have the displacement (in liters) on the back of the block behind the driver's side head. I bed yours says 5.0.
