I'm looking for a set of 6.125 rods for my 383 na build. They only need to hold up to 550hp at the crank. I'm not looking for carillo or lentz rods because I didn't win the lottery. I think the lightest I could find were the eagle h-beams that weigh 550 grams. They are a little steep at $700 but I might be able to find them used. Any other suggestions?

As far as pistons go, I'm looking at running a 10.5 compression ration so i can run 93 octane pump gas. What is the lightest piston that isn't irrationally expensive?

You could stick with scat rods, as for pistons you could get speed pro forged, or there hyperutectic pistons.

Probes are really light. I'm using a set that's for a 3.902" bore with a 1.304" compression height and they're only 351g. I may be using them with a set of LS7 rods for a total bobweight of about 1440g!!

you can get the K1 lightweight rods that are like 500g. Mahle pistons will probably be the lightest
