Cunningham 4AG Long Rods for Formula Atlantic long rod engines. These are 4mm longer than standard 4AG rods for a better rod/stroke ratio. These have a 19mm small end pin diameter (like all Formula Atlantic engines) so they will require custom pistons. These are extremely hard to find. 4th pic shows standard length 4AG rods sitting on top of the 4mm longer rods listed here. Standard length rod not included in sale.
