Ok, one more question on the Holley jetting.

I'm at 5k feet and when I first put the carb on it was in the 10's everywhere in the throttle except WOT, and that was in the 9's.
No tuneable air bleeds unfortunately.
The air bleed for the idle circuit is where I was going with it because I have everything in range now save for that just off idle cruise.
I am about 1 turn out on the idle mixture.
I'm thinking the idle air bleed restriction will still leave plenty on the mixture adjustment.

I can try the larger PV and see what happens before I do anything else though.




This would be better than jumping into modding the carb right off.
I'll recheck the vacuum at cruise and see, as I may be not be remembering it right.
I might not get to it right away though, as like I said, everything seems perfect except for that one small spot.
Now the weather is turning back cold again for a few days.

I'll tell ya, if I had a decent shop or garage I'd probably live in it.:D

Thanks guys.
Power valve is not going to fix 0-45 mph normal driving, unless the one you are running is blown.
At 5K feet you went down 4 jet sizes to get the primary cruise where you want it, the IFRs will be no different. Again you need to think of the idle/transition circuit as the circuit in your carb that operates in the 0-45 mph range driving like grandma. Drill, tap, and tune the circuit.
