Mildly modified 318 PCV valve selection

Ok
Minimum 950rpm is telling you something; don't blame the lethargy on the 12*. That cam is way too small to need or want 20 degrees, and the huge rpm drop and vacuum readings are screaming it .
Look,my 292/292/108 cam idled at 700 in a 360@14* idle timing. And I could retard it to 5*, drag it down to 550 with the clutch, and drive it in a parade for an hour. That 292 IIRC was [email protected]. And somehow your 214 wants 950 with 12*?
OK. have fun

Then tell me what I’m missing?

I set the timing at 12°

I removed the carburetor and squared out the idle transfer slots.

I set the idle screws to 3/4 of a turn out with minor adjustments to attain Max vacuum reading. But 3/4 of a turn was almost dead On like you said.

I’m getting no vacuum at the time the spark por at idle, just the way it supposed to be. Telling us the idol transfer slot is correct now.

I agree with you 110% that the idle speed seems high. My next step is to try a different tachometer and see if it’s an error in the gauge. Because it sure sounds a lot lower than 750 rpm’s in gear.

I totally get what you’re saying, and would never think of arguing with you about it. I had a big block Chevy with a solid roller cam and 30° more duration then you have, and it idled under 1200 RPMs. Closer to 1000 RPM. So I totally agree with you. This engine combo, Albeit running very very nicely right now, doesn’t make sense. LOL.

I hope you didn’t take any of my replies as being snarky. It wasn’t meant that way. I’m just telling you my results of what i did. I greatly appreciate the help you’re giving me. Thank you. Eric
