Solid Roller Lifter Question

Since I have several sb mopar projects going on right now in the shop, I weighed a few lifter pairs.

Crane solid body roller pair: 239.3 grams
Comp solid body roller pair: 268.5 grams
Magnum rollers: 303.2 grams, I weighed 2 together for comparison.

The Magnums were new replacements by Melling with no oil in them.

Thought I would post it for those who are curious.....
