Have a 502 Shor t block w merc I beam rods what do all the numbers mean on side by rod bolts,what is minum side clearnce

Post a pic, are you talking about the rod and cap stamping 1 thru 8 if so its to keep them matched up and what hole they go in

That I know some have 153,244 0008,0908,trying to figure out to post pics

never seen that, click the square next to the smiley face to post pics

Maybe grams of weight for balancing ? just a guess

If the 3 digit number is 153 and other rod is 244 that's 90 grams different in rod . You would think the rods would be closer tolerance being a high quality item t h a n k s

My guess is they are some serialization by the manufacturer of the rods.
Minimum side clearance? Whatever the service manual calls for. Or standard BBC specs.

The small 4 digit number is the number for that production run. The larger 3 digit is the rod number in order of machining for that production run.
