True I will need some rods. Thankfully I've got time. Still up in the air new aluminum rods, H beam I beam, or some stock original rods. In regards to original rods, here is what I think I've learned so far through this thread.
All SBM rods can be used with any SBM from the LA 273 all the way to the Magnum 360. There are "floating" wrist pins and "press fit" wrist pins. It doesn't matter if you use press fit or floating so long as they are all the same? Does not matter what type of crank (cast or forged) nor what type of balancer (externally balanced or internally balanced)? But I believe the balancer you choose does matter depending on the crank, forged cranks are internally balanced and cast are externally balanced? All harmonic balancers prior to 71 are for internally balanced motors? All 360's are externally balanced? Not sure if there was a difference in regards to strength between the 318/340/&360 rods. The 273 were lighter and have a little less strength?
I may be wrong on some of these points.
