Ok here is the latest. My dad has a 63 vette. 327. Same carb. Posted vacuum reads 0 at idle and 15 at the manifold. Timed at 18

Truck ran like crap on the way there. Kept dying. Tried to increase the timing to 26. Stemmed better until I drove it. Kept dying. Then I adjusted it by ear. Found whet I think may be the sweet spot. Turns out. I am at 32. Vacuum is now 0 at ported and 15 at the intake. I will be calling the builder this weekend and let him know what's up. What about hotter plugs?
