Mark,

It looks like Mancini racing has two different rods
available:
Eagle H Beam 4340 525$
Eagle I Beam 5140 229$

Hughes Engineering also has two different rods:
5140 I Beam 330$
4340 H Beam 440$
(Hmmm, looks similar to what Mancini has, but no
brand name given!)

It also looks like Crower, Manley, and Carrillo make
connecting rods for the 360 engines.

I'm just guessing that the "A" engine rods will work
in the Magnum motors. I guess I should have asked
when I was on the phone with the Mopar Tech Line :-)
Check before you buy!!!
