Connecting rod oiling question for offset grind

I took my Continental engine apart to find there were pistons that were different. After thinking about it for a while, I've decided to get new pistons but also do an offset crank grind to a smaller journal. The stock connecting rods have oil all the way up to the piston pin. The off the shelf rod I need to use does not have an oil passage to the piston pin. Will I have any problems with that? I guess I would rely on splash oiling and not do any fieldwork with it. This will be strictly a pulling tractor with probably 5hrs or less per year on the engine.

You won't have any problems. Verry few engines have pressure lubed pins, most have splash lube and some don't even have an oil hole in the end of the rod.
 
You can drill a hole in the front top of the big end of the rod. Some are done that way from the factory. On the offset I have just ground a little from both the rod and the piston till I got clearence. Vic
 
Right on what other guys said, drill a .150" size hole, but put a bigger chamfer on the hole to create a "cup". If you ever seen an oliver rod they have the on top of pin and on each top side of journal for "splash" lube

I will try and get a pic for you
 
this is a 44 MH rod
