I eventually had to open up the low speed or idle bleeds to get everything just right.

I really don’t know what it is set at, I will check it tom and see what I find. It could be the converter, but I am hoping not right now.

PKRWUD-
I didn’t mean to say I wondered about installing the 3.5 power valve. According to Holley’s way of thinking, the 5.5 would be what my vacuum in gear called for.
