[bigdaddydon]

hey there fellow mopar guys and gals. i have a question i haven't been able to find an answer to. did the 340 come with a mechanical cam in any version besides the aar/ta? i also can't find any reference to the part numbers on my adjustable cast iron rocker arms. the part numbers are, 2465380 or could be 2465880. any help would be appreciated.
thanks

I believe all 340's were hydraulic cammed, stamped steel non-adjustable rockers(Except TA). If you have adjustable iron rockers, they are either after market, or 273 solid cab adjustable units. I have heard you can retrofit these to the 340 if your pushrods are the correct length and they don't contact the head passages from high lift cams.
