After many months and many $, I completed the installation of a 95 LT1/4L60 hydrolic with the original computer, sensors relays ect. into my 69 chevelle SS convertable and after a few years on the road I wish to improve it's performance just dealing with the upper part of the motor without changing the cam (if possible)

Any one of you guys have the specs of the original cam from a 95 LT1 motor. And the rocker ratio.

I'm thinking of buying RR 1.6 ratio, is it going to fit under the original valve covers.

Is there any work to be done with the intake/plenum while I'll get my heads done (pocket porting and 3 angles valva job) beside port match heads/intake.

I already have headers and improved ignition and afpr

Thanks in advance for the time

You could port the intake, or look for an LT4 intake to replace it. I guess you already said port though.. I can't comment on all types of rockers, but I know some will since LT4s had aluminum roller rockers.
