I have what is prety much a clone of a 322 CI 312 that Ted built a few years back and was featured in the March-April Y block magazine. Mummert heads, custom Isky cam, Sharp roller rockers, Blue Thunder Intake. Need to have my factory tach drive distriburor re built and need specs for a good advance curve. Distriburor was converted to dual points and I then installed a Pertronix III, Need advance curve advise and someone to re bush and re curve the distributor. I am running centrifical advance only. No vaccum advance.
