Edelbrock Experts I need your thoughts

I agree with Ddaddy putting in a metering rod like that will reduce the step from cruise to power and should help smooth out the throttle transitions. I think that leaning out you get when you gradually open the throttle is the actual mixture you're getting just through the cruise mixture on the primaries, which is too lean. I would first try the 65x47 rods (much easier/quicker) and see how far it changes the AFR and if it needs to be richened back (probably on the power circuit) then put in the .095 primary jets.

Anybody got a link to that thread comparing the 1406 and 1405?

Here is the link I had saved. Another 1405 vs 1406 thread

Try this combo...
Metering Jets - Primary .095, Secondary .098; Metering Rods - .065 x .047

I think the secondary jets are where the biggest part of the issue lies.

After thinking about this combo more. I have the feeling Im going to be way to rich on the cruise circuit. I had the 98 jets in with a 71/47 rod and my A/F was in the 11's. I have the feeling if I go to a 95 jet and a 65 rod its going to be worse.

Here are the combos that I've tried so far and the rough A/F readings each.

Stock 98-75/47 A/F 14.0-14.5 WOT A/F 12.5-13.0
98-73/47 A/F 13.3-13.8 WOT A/F 12.0-12.5
98-71/47 A/F 12.7-13.0 WOT A/F 11.2-11.7

101-73/47 A/F 11.0-11.7 WOT A/F 10.0-10.3

92-68/42 A/F 14.0-14.5 WOT A/F 12.5-13.0

Now all the combos above (with the exception of the 101-73/47) started to lean out the second I stepped on the throttle. The richer the combo in the cruise circuit the less it leaned out. The other odd thing is with the first 3 tries, even though the power side stayed the same size, it got richer.
