Ported vavumn is only needed foe emissionsthat is why they the factorys came up with it in late 60's so engines could pass idle emmissions. MY $0.02 if you go to trouble of finding what engine likes with advance curve and total advance,why would you want to add more advance with ported vacumnas engine speed goes up ported vacumn will rise and add advance.
A high proformance engine needs manafold vavumn at idle,then when you floor it the engine will only receive the advance you set into the dist + static inital advance, under light load as you cruse down the road vacumn advance add to this and helps fuel milage |
