Rocker arms

[nicolasconnor]

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

I don’t recognize the numbers, but I’m pretty sure ‘74 440 rockers will work on a ‘64 426 street wedge.
