8.5.2 Early GM 305 cars may use up to 1.6 ratio individual stud mounted roller rocker arms.
Is that for carbed 305s or for TPI 305s also? And what kind of power difference will it really even make?

1.6 Rockers + shorties = 10hp on my 305 TPI .

Did that effect your torque very much?

Now I have a question about the power chart for CMC2, it says Early 305 TPI add 5lbs to torque colum....does that mean instead of 310 TPI motors are allowed 315 maximum before adding weight?

No, that just means you start off at 3250lbs.
Ok, not really. You are correct.
