I bought a 3
cyl block from a guy last weekend. When we were negotiating on it I asked him to measure the bores.
He replied that with a tape measure it looked to be about 4 13/32"
That was close enough to determine that it was a 4.4 and not a 4.2.
Got it home and was doing some more precise measuring on it yesterday.
This block is dusty like it's sat for a long time. Has slight surface rust everywhere including in the bores. Nothing I was concerned about but I took some fine emory cloth and sanded the bores a little.
Then I used a snap gage/mic and measured them.
I am consistantly getting ~ 4.395"
That got me wondering so I wire brushed the deck. It has NOT been sleeved.
Am including a photo of the # that is stamped on the right side pan rail.
I have a set of new gas pistons from a school engine I will use in this.
The skirts will not go into the bores - or maybe could if you forced them in but
not with proper clearance.
Does anyone know what I might have?
Could this have been a replacement block from the past?
I would think the bores on a replacement block would have been 4.4000.
What does the stamped # mean?
Thanks
