Re: advance curves
Brian if you look in the ford service buletins book, the big thick one with the steel covers,under ignition there is a very detailed list of all the curves,if you dont have it let me know and I will shoot you one.
also I made a machine so I could spin up the dist and its an easy job to map out the curve from there,
What compression ratio are you using,
The vac brake will not alter the curv but will slow it down ,from memory about 5deg,
another thing you could maybe do is fit a space under the little leaf springs to stifen them up.
