Is 16" vacuum at idle too low for my veh. (see sig.) Its the best i can do right now ,should i consider a resevoir or something?

 

16" at idle with the XE-268 cam in a 350 is about exactly where you should be. Plenty to run power brakes and such.

 

cool! I just went out and reset the idle ix screws to spec and did as edelbrock tech suggested to get rid of my bag (1/4 turn ccw) but it made it slightly worse so i went the other way i"m now at 1/2 turn cw from stock and it seems better i'll go out again tomorrow as i was gathering attention and i dont want that I'll keep posting results
