the only way to tell if 5.3 or 4.8 is by the serial number, from the outside
the only way to tell if 5.3 or 4.8 is by the serial number, from the outside
1987 jeep wrangler, 1999 LS 1, 4l60 231j transfercase, dana 30 frontend ford 8.8 rearend 3:73 gear ratio. sandersons shortie headers, 2.25 inch exhaust into 3 inch flowmaster muffler.
I went through that already the serial # on the block is 12551358 which comes up as a 4.8 / 5.3l block. doesn't help me at all really. Seller contacted me back. its a 5.3l
12551358 isnt the serial number... thats the part/casting number.
the serial number would be a etched number that coresponds with the VIN#
of the vehicle it came from. usually a dot matrix etching.

Where would I find this number at?
Driver side back of the block just under where the head bolts to it.
Thanks, I will check it out tomorrow.
