Greetings all!
Rebuilding a 1.7 for simple daily use. Crank is going to Rimco, running CB street cam with dual Weber 40s. On to the rods. Looking at the H-beam but not sure I need all that. Read that the stock connecting rods are beefy enough but the bolt are often the issue. Go with rebuilt stock rods and ARP bolts? Thanks in advance! |

Not sure about the bolts never read about any issues with normal use,some folks say the nuts need to be replaced each time but I never have unless they are damaged @ the threads. You don't need 'H' beam rods,EMW offer rebuilt sets for a very reasonable price and no cores required. |

I read something the other day about the need for H-beams. I got that they are more for racers, doing high revs. Seem to be for the weight reduction and strength. Less weight = more HP. So OEM rods are strong but heavy. So the poster felt that they were fine for a street upgrade. Would be easy to balance them and the whole rotating mass once you have everything out. Same post did suggest replacing the rod nuts, no mention of bolts.
