My rods were 732 to 752 grams. Same number rod. Not a chance in hell of using both of those in the same motor. Another 1 the big end was way to heavy. Needed to change that 1 also. There was a discussion b4 about u may have to have multiple sets of rods so u can find 8 the same. Kim

Well now, hold the phone on this info... those rods of Kim's had the beams ground down on them quite a bit....so they are hardly 'factory rods', and can't be used for comparison to actual unmolested factory rods, which is the subject of this discussion.

I've weighed a few full sets of stock rods and they all fall within a tolerance of 5-9 grams and wiht the big and small ends measured, the effect on bobweight from their big and small end variations is in the range of under 15 grams max to min. I am sure that there are some sets out there with larger variations.

The OP should be fine in putting in another unmolested factory rod.

Might do some more research to see if there are rods and pistons I can use that are full floating and the same weight as the stock pressed pins,pistons,and rods. I'm not a huge fan of the pressed pins.

The number I have for Magnum rods is 744 grams, total weight each rod. SCAT and Eagle I beams are around 600 grams + or -, total weight each rod. So it looks like you will have to have the rods bushed if you want them floating.... or just honed out and floated directly in the small ends.
