Since you did not specify what year your Z28 is, may I offer my opinion?

If it is later than a mid 1970's car (there was a body/chassis change in that era, somewhere), and even if it is an earlier one, for all intents and purposes, stick with the "juicer", or go find a different car, one with a clutch and a stick from the factory. The concept is not an impossible one, but the hassles of the conversion will far outweigh the benefits; if there are any, in true fact.

This is a purely practical opinion, from an old "greybeard". I do understand the thrill of "rowing the stick", and the rush of the positive hook-up, and still do it myself, from time-to-time. But, in a daily driver, and a car already designed, engineered, and built as a "self - shifter", it is far more astute to use what is there already, and add to it (read: improve it) with a performance rebuild, or modification, than to try to re-engineer/re-manufacture it to be something else.
