84 6.9 IDI block serial # help


Hi all new to the forum but needing some help I’m having an issue locating my engine block serial # recently bought an 84 with 6.9 the guy says it has a newer motor in it and I’m hoping it’s a newer style with the thicker block around the block heater.

Any my clue what year the block was made?

I’ve found one # located by the timing cover but can’t find any info about it any help would be appreciated

Looks like you have the earlier block, don't sweat it though I've had several of these engines and never has a problem even when plugging them in all winter.

If your worried just don't use the block heater it's that simple. The only engines to be cautious of are the 83's. First year is a headache for any motor

Is this a reman install or something? Looks like it's not the original serial number stamp.
