[35regal]

i took these of my 340 engine, i couldnt help but notice the w-2 stamping on them, i know they are not off-set, are they STANDARD W-2 ROCKER ARMS??? I ALSO HAVE WHATS CALLED I BELIEVE BANANA GROOVED ROCKER ARM SHAFTS, ONCE I CAN GET A CONFORMATION ON THE ROCKERS I WILL LIST THEM AND THE PUSHRODS AND SHAFTS FOR SALE.ARE THESE STILL 1.5 RATIO?? THANKS FOR YOUR HELP, BRIAN

35Regal,

Yes those are forged and durable enough but check the ratio. Out of about 200 that I have had they checked from a low of 1.41 to a max of 1.51 . Most were in the 1.45 range. Not accurate enough for my engine. The small Mopar loses a bunch of lift anyway from it's poor geometry. Pushrod and lifter not being in plane with each other. This offsets and tilts the pushrod enough to lose just about .010 from what the lobe transfers to the pushrod side of the rocker arm. Increased ratio's can help restore this. Good luck.

Those are 273 rockers. I am looking at my original 273 rocker arms right now and they are exactly like those. I hope this helps.
