Holley power valve sizing.
 

OK - it has been a long time since I had to tune a HOLLEY carb.
For some stupid reason this engine is running way rich in the Daytona and it ran perfect in the SCARAB.
I am running 1050* F at 3500 RPM and 1250* F at 5000 RPM
I am fouling out the engine.
It idles at 5 to 6.5 inches mercury.
I forget what number power valves I need - I am thinking 45's
It's a HP950
Gonna have to mess with it tomorrow.
The new engine is going to be fuel injected.
I bought a O2 meter but havn't gotten it hooked up yet.

Run a power valve 1/2 vacuum reading at idle. He's a link to holley power valve tuning http://forums.holley.com/entry.php?4...r-Valve-Tuning

Those vacuum readings are pretty low. Big cam?????

ditto sounds like vacume leak
