Using the original 4053 carb.,rejetted, and the point type dist. w/ a Pertronix module in place of points, 37 degree total timing all in at 3000 rpm.
93 octane gas and 5 gal. of 100 octane aviation gas added to the tank. Quench on the chambers is .035 Vacuum at 1000 rpm is 5 in. Not loading up at idle, but I only have 1 hour break in time so far, mostly at fast idle 1200-1700 rpm using Brad Penn break in oil with zinc. So far it is running good and smoothes out nicely as rpm's come up a little. I am going to fine tune the dist. a little more this week. My 69Z is an early build factory chambered exh. car so I don't want to change that, keeping my exh. manifolds and smog equip. on also. If I don't like the way it performs on the street I will change it back to my .030/.030 cam.
