There are basically two versions of connecting rods used in the big block Chrysler. "B" (low deck) blocks used a 6.358" version, for which there was only one casting number, 1737692. "RB" (raised deck) engines used a longer 6.768" rod, of which there were several different versions available, with different strengths and casting #'s. All stock production big block wedge rods use the same bearing and pin size, along with 3/8" rod bolts.

Connecting Rods RB with Capscrew bolts - Set of 8
Shown above is our BRAND NEW 5140 forged steel stock replacement AND performance rods. These rods use a 7/16" capscrew, a premium design borrowed from our high end H beam style rods, which is much stronger than the older factory style "bolt with a nut on the end of it." Finally, a rod that works great for stock replacement press fit pin applications as well as high performance engines at an incredibly reasonable price. Forget about reusing 40 year old stock rods! We now have an option that is many times stronger for considerably less money! The beam shape and size on these rods is modeled after the famous (and super strong) 426 Hemi rods. These rods use a non-bushed small end for factory size 1.094" press fit applications. Length is factory RB at 6.76." Both the big and small end housing bore are finished to precision tolerances on AMERICAN MADE Sunnen Power stroke honing equipment. One other important fact to remember is that metal has what is known as a fatigue life. Everyone has bent a paper clip back and forth so many times until it breaks. Once it breaks, it has reached enough "cycles" to get beyond the limits of it's fatigue life. Connecting rods are also made of metal and also have a fatigue life. Every time the piston fires, the rod is compressed and every time the crankshaft turns back around, it drags the piston back down from TDC. This causes the rod to expand and contract, or "cycle" just like bending the paper clip back and forth. The only difference is that the rod is much stronger than a paper clip (unless maybe you're talking about Ford rods) and it's being cycled millions of times as the engine is running. The more cycles on the rod, the weaker it will become, and the closer to failure your engine will be. These rods are BRAND NEW, so they will always be starting with ZERO cycles on them. That alone is worth a huge amount of strength. After forty years and thousands upon thousands of miles, do we really know how many millions and millions of cycles those old factory rods have on them? With the cost of cleaning, magnafluxing, resizing, buying new bolts, etc, etc with a set of stock rods, going with our new aftermarket version is a no brainer!!

B1094

Pin Bushings - Reduces 1.094" Pin to .990" Floating-Set of 8
Use our B1094 Pin bushings when reducing any Chrysler 1.094" pin size rod (stock or aftermarket) down to a fit a floating .990" pin setup. Or, they can also be used as service replacement bushings in aftermarket H-beam type rods with .990" pins. These are .060" wall, for plenty of rigidity. They require installation by a machine shop, as they must be pressed in and sized to fit after installation. We usually recommend about .0007" pin to bushing clearance for most applicatons. Sold in sets of 8.

BLEM Connecting Rods RB with Capscrew bolts - Set of 8
We have a few sets of our 200-1132 rods where the machining on the pin hole was a tiny bit out of spec. These work great for applications where you are floating the pins or installing our B1094 pin bushings. While these are still suitable for most applications, we are offering them as BLEM items since they are technically out of spec. All other areas, machining and weight matching are within spec. We are offering these as a clearance item at a special reduced price while they last. Very limited quantity available. NO RETURNS OR WARRANTIES on clearance items or blems.

BLEM Connecting Rods B 383/400 with Capscrew bolts
We have a few sets of our 200-1149 (383/400) rods where the weights were not closely matched, or where the pin end was honed a few ten-thousandths bigger than spec. These rods are still useful for floating pin applications. The small end can be honed for the floating pin, or our B1094 bronze bushings can be installed if desired. We are offering these as a clearance item at a special reduced price while they last. Very limited quantity available.
