Before any bent pushrod symtoms a pushrod replacement is recommended for modified injectors larger than a stage 2. Why not upgrade them with the Smith Brothers performance pushrods? Push rod failures result from high cylinder pressure created by big performance injectors during high motor revolutions. These stronger push rod are much less likely to bend at the higher RPMs. These are recommended for anyone using a hybrid injector. They have 3/8" 4130 Chromoly tube, 3/8" ball ends and are stock length. These are a great upgrade with ARP head studs and Comp 910 valve springs. Bend pushrod symptoms are: missing popping out of the intake or exhaust rough running and idling
