Results from todays road test.

1. Off idle is good. No sign of detonation. I put a vac hose on my stethascope and laid it on the intake for the test drive. WOT is the most powerful I have felt with this engine. Everything works really good. The engine pulls hard to 7000 rpm.

2. During full braking the engine will die. Anything short of a panic stop and it will not stall. I think it is pretty close.

Jim's settings worked pretty well for me.

I now have 16 degrees initial timing with 38 degrees total. My vac advance is hooked to full manifold vac below the throttle plates.

Both floats are set at about 1/4 above bottom of the sight glass. Both transfer slots are exposed about .015". I get 15 inches of vac at 900 rpm idle.

I am some what concerned about the amount of total timing advance. I will call Demon and Edlebrock tech lines on Monday and see if they know how much total advance worked well in their test mules.
