I'm using stock 340 bushed rods with ARP bolts in my 625HP small block 383 dirt track engine. That's what was in it when I bought the engine however they will not take cold starts with heavy 50W oil... the resulting carnage proves that.

I really like the I-beam Oliver and Crower rods... good stout pieces. Mu buddies have used them in their engines for three seasons without a failure. Carillo's are also good.

I'm using some used NASCAR Pankl rods in my Gen 3 build when I get to it. The have small, lightweight pins and a narrow Honda big end. Weigh in the range of 450 grams IIRC. The nice thing is the price... you can find them on Fleabay for $125/a set or less. Good stuff.

I was going to use a set in my LA engine but I didn't want the expense of repairing my damaged crank ($300) plus the cost of grinding the rod journals to Honda size plus having the nitriding done, too... another $250.00.
