Chevy 327 Connecting Rods

While you are replacing your engine pistons it is a good time to also upgrade your rotating assembly by installing modern connecting rods. Why risk damage to your freshly rebuilt performance engine by installing used connecting rods that have been through who knows how many engine cycles and stress.

With the high cost of machine shop service these days you can often upgrade to far stronger modern rods for not much more than the cost of reconditioning a set of use rods.

327 Connecting Rods

molnar technologies 327 connecting rods

Molnar Technologies H Beam rods are machined from billet 4340 steel, and then heat treated to provide improved strength. To make the rods even stronger, they are shot peened to which also increases fatigue life. All Molnar connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set includes ARP fasteners, moly lubricant and installation guidelines.

All Molnar rods are finished in the United States at the Molnar Technologies shop in Michigan. Critical rod dimensions are are held to very precise tolerances of +/- .0001 of an inch, which is the tightest tolerance you will find in the performance and racing aftermarket.

NOTE: Be sure to select the connecting rod set to match the rod journal size of the crankshaft you will be installing these rods on.
