In the budget rods your looking at, let me say you can save about 70-80 grams in the I-beam rod over the same spec H-beam...
I have run the cheap RPM rods in a few engines, and they worked great...
I found a guy on ebay selling rods for like $250 which are the same rods everyone else sells for hundreds more....
I would run these in a heart beat in a application like yours Randy... Just have them checked of coarse, never had a single problem yet, other than the small pin needs honed...
Thats common procedure with these....
Shoot me a I will jump on the old computer and dig up that ebay link for ya...
