here we go again. i vote with denny. iscoresports most sbc come from the factory with vac. at the dist. at idle. some people dont think thats the way it should be so they run ported vac., so youll get 2 dif. answers on this ?. me and denny always run manifold vac. most of the time. ive all ways run vac. there because thats how GM taught me. try it both ways and see which way you like it. it wont heart anything. use the same base time.
