Yes, 318. I went ahead and ordered the FBO plate since I'll benefit from it anyways. Is it possible to assemble the distributor to where it will advance non stop?
In practice, yes. Use heavy enough spring or springs and timing will continue to advance to redline.*
If you look at the advance curves of pre-smog engines, the more efficient low rpm engines have a long curve that follows rpm.
If you look at the pre-smog curves of the higher performance engines, they advance quickly and then have a somewhat long slow curve.
*Its really only useful to have it advance to power sweetspot.
