Stock Rocker Ratio?

[JMSII]

Ok, dumb question...what is the ratio for stock stamped steel AMC V/8 rocker arms?

Is it 1.6?

Thanks!

Yep, all the GEN3 (70-up) heads are 1.6, the GEN2 heads (67-69) are 1.5 (I think).

Thank you!

Gen I engines (250, 287, & 327) were 1.5. All Gen II & Gen III (290, 304, 343, 360, 390 & 401) are 1.6. The design specs on the later heads are so close to a Windsor Ford that it makes the use of rocker arms for those engines a drop in.
