HI all... I'm thinking of either replacing the rocker arm shaft assemblies - or having them rebuilt - on my 340. I see some places sell 'high performance, lightweight, roller-tip' rocker assemblies for 215's... so.... will these work on a 340 or are the assemblies different? If having them rebuilt is the only option, has anyone had this done or could anyone recommend where to send them? Thanks!
TRW sells rebuilt rocker arm assemblies - or just go to www.buickfarm.com & buy the arms & shafts (if they still have them) (that's what I did, it was about the same price as TRW) or http://www.rockerarms.com Good luck
