If you buy new rods, as I have done many times, I recommend RPM H-beams. They're $400 shipped. They're much lighter & stronger than cast rods. They are available for press-pins or bushed, for floating pins.

Cliff has posted here several times that he has used several brands of Chinese H-beams, and they were all good.
Curious, what was the total cost to have your rods resized, including the ARP bolts ? If you don't know, PLEASE ask the shop & post that info. There are guys here, on a regular basis, who are trying to make the decision of what rods to use. When the 5140 rods were barely over $200, it was a no-brainer. Those rods were apparently discontinued. Similar 5140 Eagle brand rods are nearly $400. So knowing a CURRENT cost for having stock rods resized should help guys make an informed decision about rod choice.

PS: Paul Carter did a 400 engine last year, that used cast Olds 455 pistons. The owner said that Paul had to remove some material from the cast rods, because the small end was slightly too big for the Olds pistons. He said he didn't know the cost of the extra rod work, because it was just all included in the machine shop cost. Told me to ask Paul about the details. I sent a PM to Paul several days ago. No reply. I reckin he's busy building engines. Have noticed that he seldom posts here anymore. May be tired of giving out free info. OR may just be too busy.
