SCE has some Copper, I do not remember the part number but I needed a set one time and they had them.Yea, that is what I am going to do. Sucks I wanted to assemble this weekend. I talked to the machine shop today, they told me they left extra just in case I had a problem. Funny they failed to mention this. I hate having to baby sit them.
Go with the .030", you will be happy you did4130 h beams, .018 in the hole. My target quench is .037-.039. I will not defer more than .002 tighter, or .001 looser. Just my thing. it is a circle track motor, so every bit counts.
Funny thing is Eagle can not hold a Tolerance to save their life, I have only used Scat's I Beam Pro Comp with the 1.400" under head length 7/16" bolts with zero issues.biggest I could find was for a 4.1 bore. No offense to scat, but I despise thier rods. If I must use chineese rods, only eagles. I have never seen a failure from thier rods. Now the finish work on thier cranks.... thats another story.
