What kind of cam are you putting in it? I would suggest staying mild, something like a HO 305 Camaro cam. Ask the machine shop, but those small engines do not like a lot of cam, won't make much vacuum for power brakes if you do. HO 305 cam is like 403 in and 415 ex. I forget the duration and lobe seperation, it is slightly bigger than a stock 350 cam which is 390 in and 410 ex. Are you running a 2 barrel carb? How do you crack an intake manifold? Does this guy build hobby stock race engines? Old stock Chevy 2BBL intakes are worth bank to these guys for some reason. I swapped 3 of mine for some cast iron 4BBL intakes for Qjets and the guy was practically overjoyed to get them. Not worth much to me, I would rather have the Qjet and drive the primaries most of the time and still have the ability to tromp on it if needed.
