Small end of the rod (wrist pin hole) is narrower (width) on the Magnum.

The Magnum rods also weigh less than the LA’s. Some LA’s are full floating pins also and not press fit!
Magnum left, 744 grams, LA right. 756 grams. your results may vary.

I weighed mine and they were all within a gram of each other, 744-745. Even weighing the big and small ends they were pretty spot on!

According to Mopar Stroker Book, ‘92 was the first year for the Magnum rods.. they’re listing it as 92-03.

I'd use the LA rods over the magnum rods any day.
Well, that's a super simple statement. What IF the selected piston is constructed for the narrow pin end? Dude, there's more to it than ANY **** WILL FIT.

Simple, la rods, use pistons for the la engine
IF you have a Magnum engine, with Magnum rods, ARE YOU suggesting that those components need to be turfed for, please explain, what reason?
Just have the LA rods narrowed on the small end. Any competent machine shop can do it. I'm not advocating one is better, as I don't know, I'm simply saying if all you HAVE are the LA rods they can be easily made to work.

I know I'm right....
I bought MP stroker pistons and guess what? Magnum width...OUCH! That's when I found this out. I guess the lack of a floater pin groove was the 2nd clue....

Arrgh. Swap meet? Or custom? Can you return em? So they were full floating pins and the c clip Grove weren't cut?

No they were NOS STD 360/5.9 4.00 bore from a seller on Racingjunk, got them for pennies on the dollar as he was a Chevy guy and this was in a purchased storage locker so I pulled the trigger, I didnt even have a 360 or a stroker crank but you got to start somewhere! Of course they were circa 1992 IIRC and long out of production. No problem, they were only about 2mm short of fitting the LA rods so I just got creative and ground the LA rods I had on the one side that hit and went with that. Hot rodding......
