Thread: 1.5 inches of vacuum

You can use the same cam with the new lifters , you just have to break the cam in again like a new one to use the rhodes lifters.....just pull the intake.
Moving the cam one tooth on the timing chain will not hurt either.

So I tried with the intial timing at 12 degrees didn't help with the vacuum do think I should go some more. I checked it at 3000 rpm its only about 28 degrees shouldn't it be more than that. Also it wouldn't turnover very good so tommorow I'm going to put a new starter in it. It also seems the left side exhaust seems way more raspier almost annoying compared with the right side. I have upright headers it just seems ones different sounding than the other. I just have pretty much stock ignition except a mallory hei replacement distibutor.

What if ain't using my vacuum advance, I never have, don't really know the reason. Should I try it. I just figured at wide open throttle the vacuum drops to 0 so vacuum advance really wouldn't help. But should I just hook it up and run it up to 3000 and see what I have. Thanks

Just another thought, should I try to go with a better ignition, right now its just all stock hei ignition. I've read if your running race gas that you should have a little better ignition. Maybe that would clean up my idle a little bit and help through out my rpm band. Also would elavation change my vacuum, say about 2000 feet higher.
