Problem hainging rods I'm finally starting assembly on my LSx motor and ran into a snag. I'm using the Howards Billet connecting rods with a set of Custom diamond pistons for the LSx. The problem is in the area between the small end of the connecting rod and the piston. When you put the wrist pin in there isn't enough clearance between the piston and the rod, the rod actually rubs the bottom of the piston. What is the best solution for this type of problem? Thanks for any help!

So Diamond just has a very narrow pin boss spacing in the piston you have now then probably. I got a set like that for big NOS with the pin boss spacing only like 1.095 ish with the 1.060 wide rods made for a very tight fit indeed. The ones I have are a taller compression height deal and they still worked alright but it was very close. I had some older SBC rods so I had to mill the rod back on one side a small amount to make them happy.
