All very sage advice -- thanks! I had resigned myself to not obtaining that block replacement WRO back in 1980. But when I just recently discovered the CRG forum and began reading all of the incredible research material posted on it, my hopes were once again raised that Chevrolet might have "opened their files" for the enthusiasts and older production and service records were obtainable, somewhat like the kinds of information the Pontiac Division provides for owners of older Pontiacs. Oh well, maybe someday. But yes, I have thoroughly enjoyed the car since '79 and have changed the rear gear several times before, once again, settling on the original 4.88 ratio my car was born with. The one change I have no regrets over making was the addition of a 5-spd O.D. about 6 years ago. The box I chose was the then brand new SS-700 that Kiesler was marketing, with the internals produced by Legend Gear and Trans. I have serial #200 unit, which fits like a glove in the tunnel -- no mod's to either the tunnel shape or shifter cutout were required to fit it. This box has a 2.66 1st gear and an 0.69 5th. With my 4.88's, I usually am shifting into 3rd before crossing the intersection but I can actually drive my car on the freeway! I've fitted temp sensors in both the trans and rear diff that feed a single Autometer temp gauge through a DPST switch to keep an eye on gear lube temps at speed.
Has there been any research completed that either estimates or documents the number of 1st Gen Z/28's ordered/built under the 9511 COPO with the 4.56 and 4.88 ratios? Or is this a question I should ask in a new posting?
