The reason I ask is one from experience and curiosity. Having worked for generous Motors Powertrain through the 80's and 90's and performed countless VE maps for the new (then) Quad 4, I cannot imagine anyone masochistic enough wanting to do this correctly. Correctly meaning A/F meter, Tow Dyne, test track, time to do it, etc, etc. I personally built a '74 Monza with a 262cid and scratch built using a '69 Z28 intake with 2 TBI units. I don't remember how many set of brake pads and rotors I used up trying to grab all of the VE table points. Congrats to those who have successfully done this calibrating. tnx, Mick
