Eagle SIR6123CB rods Vs stock.

He's not going to have an issue with a stock rod at 400hp. Wake up to yourself. He asked for opinions and he got them.
Personally I like to give my money to fellow Aussies for their work, not ship it overseas if I don't have to..
If the guy want's to spend more than he needs to, to get the job done then that's up to him. Stop ya cryin..
