I recently saw a picture of a '68 289 with a dual port distributor in which the rear vacuum port was capped off.
That got me wondering.......since the rear port is for emissions and most emissions controls rob power is it safe to assume that capping the port would increase power or do the 2 ports need to work together? Would I be better off just replacing the double-port module with a single port unit?
Thanks for any insights.
