Hello , I saw that the bearings are not in the middle of the rod. My question is now :

Should be the bigger space for the oil in the middle between the 2 rods ?

I read in my book that the side with more space should be on the right engine sinde in front, and and the left side rods with the more space , backside.
Sorry for my terrible engish, I hope you know what I mean.
Thanks for help

Are these stock 351C rods? The stamped numbers should be facing outwards for correct orientation. You will notice that one side of the rod end is flat and the other side has a chamfer. The flat side is designed to be placed against the other rod on that crank journal. The chamfered side is designed to be able to ride up along the crank journal. The stamped numbers on the stock rods are designed to make this happen.

The oil squirt holes will point towards the opposite cylinder bank.

Hi Julian, yes stock rods.
Sorry for my bad english , what is a chamfer ?

On the top of the rods , there is one side with more weight/ material than the other side , do you mean this ?

My rods are not stamped, and all the parts were mixed togehter by the pre owner of the car, so for me it is verry difficult to put the engine togehter.

small block Ford engines, including the 351C, have narrower bore spacing than the small block Chevrolet. Due to this the "big ends" of 351C connecting rods are narrower (0.830") than the big ends of small block Chevys (0.940"). A 351C rod journal is 2.31" diameter and 1.66" wide, whereas a small block Chevy rod journal is 2.10" diameter and 1.88" wide.

It was once popular to off-set grind the 351C rod journals to 2.10" to achieve 3.70" stroke, and to then use 6" long Chevy rods which were modified by machining one side of the rod thinner so the Chevy rods would fit on the narrower 351C journal.

Could this be the case with your engine?
