Rocker arms

[MARTY JONES]

Does these numbers ring a bell with anyone,t511,t51,stamped on rocker arm,they look the same as original 426sw.,only alittle more heavy duty. I think they are from 74 440, can i use them on my 64 426sw

Should be no problem.

Thanks, do u know if the rocker arms with the no. T51 and t511 are o.e.m.,or from another company. Thanks

I recall seeing those markings before but can't say for sure. I bet they are OEM.

If I remember correctly T-51/ T 511 should be the temper treatment for rocker arms...
