A source for connecting rod bolts?

Post by whitehause » Fri Jan 11, 2019 6:53 pm

Anyone know of any source for connecting rod bolts and nuts? And not AR.....27.00 per bolt is out of the question.

Might as well be ARP at that rate.
Or good used from another motor. They tend to hold up well in my experience.

I checked ARP, they don't offer them unless they cross over to another vehicle.
I'll have to measure the stretch on mine and see if they're within tolerance.

I have used ones, was hoping to find some new available at a reasonable price. I emailed ARP to see if they offer anything that would cross over to the fiat bolts.

--Tim, 2L rod bolts are very robust. Just compare torque spec: 55ft/bs for the 2L, and 38ft/lbs for all others. I would not hesitate to re-use 2L rod bolts, unless they have been re-torqued more than 4 times.

--At one time, I ran stock rods in 1608 and 1756cc race motors. All TC motor rods are very robust, and extremely well balanced from the factory. We would even further lighten and rebalance the factory rods, using the GC bible as a guide. Shifting at 8400 and running routinely at 9000. Eventually, I had a stock 1756cc rod bolt fail. Very costly. I researched and discovered that I could use an ARP rod bolt for a 351 Cleveland in my 1756cc rods, simply by honing the bolt holes by 0.015". They worked perfectly.

--I ran the stock rods with ARP bolts for about 2 more years (with 0 failures), until I finally just bought some good, aftermarket rods, and saved all the lightening, re-balancing and honing, and cost of fancy ARP bolts.

I have one that's dinged from hitting the aux shaft, so I'll need at least one.

Heard back from ARP and they said they don't have a direct crossover, and don't plat to manufacture any rod bolts for the 2L connecting rods.

With that said, does anyone have a good used bolt or two they'd like to sell?
