Quick,
Your going thru the the same problem I had when I built my 302 Jimmy. The Hudson rods and L6 Chrysler bearing combination has worked well. The engine has seen 6000 rpm numerous times with no problems, and the bearings look perfect. You can talk to JE and they can make you a set of pistons like mine with, or without, the dome. If you have a custom set of rods made stay away from Howards Rods. I tried to get a set made by them and finally had to turn it over to a collection agency to get half my money back.
Good luck, Ron
