Many years ago, like 30 i had this happen, I had mopar racer friendfix it at his shop, Hes deceased, so I cant ask what he did. The cover actually came off a 70 340, now I couldnt tell you if it was a for sure 70 cover, but it looks like my 72 cover. Here's a pic rotor towards 1, piston at top...

member: 44618"]I see you're adjusting screws are a miss matched set. You have some screws with nuts and some interference fit screws from Factory 273. You need to buy a couple more adjusting screws with nuts from Summit Racing to complete your set. You need to remove those rocker arm shafts from...

So i have notch backwards?

Pushrods for hydraulic cam,

Got the comp cam ones,used with those rockets

Excellente

Wanted to make sure its all correct, that being said notch i believe is down at front of engine on passenger side, the oil holes should be angled at springs, Correct?

Thanks

Installing these rockers from 273 on 340 is this correct set up,I didn't find a picture

Thank you

The 273 shafts appear to be the same as the hydraulic shafts on my 72 340, but the oiling holes are mutch larger on the 340, can the 340 shafts be used with the adjustable rockers, I was just speculating that there would be better oiling with bigger holes, or should i stick with the 273 shafts?

Thanks but I just paid another member for one, Eric.

I need at least one good 273 adjustable rocker arm

Yep

Too much detonation on the mp purpleshaft

Lots to soak up there, its been running an average 180 *,
