Merlin manifold and single 750 Holley double pumper. This motor was initially built with an 8-71 blower and dual 750's. The carb has 74 primary and 86 secondary jets, 6.5 power valve. There's between 6.5 - 8.5 vacuum at idle and in gear. I've adjusted the idle mixture's to get the max vacuum at idle in neutral which is 14.
Any help is appreciated, thanks.
