Need some FE Help

The holley site only shows the driver's side to prove it independantly, but mine does...

Good point on the manifold vacuum. I should probly start there before i pull the carb and try the 1406 or 1407 edy carb...or try adjusting this holley.

Most Ford Durasparks have an adjustable vacuum advance. Insert an allen wrench into the vacuum canister opening.

Dave,

IMO, driveability will be enhanced with ported vacuum, as well the ability to control detonation.

JMO,

I thought it was a 660 center squirter. I was corrected on the FE forum, it is a 450 CFM, but still designed for the 2x4 intake.

So I tried manifold vacuum, still pulled 12 hg at idle.
Pulled the 450 and put on a used rebuilt 650 vac sec Holley i had and the vacuum pull was way down at idle. It sounded OK. Turned it off and got ready to start tuning on it when i heard dripping. Hopped up and looked down the throat, and it wad dripping out of the squirters.
Pulled the 650 off and dropped on the 750 edy. Started and ran like a champ. Did some fine tuning. Pulls zero vacuum at idle, and didnt piss itself when not running.
Still had a little irratic idle and stumble at about 2k rpm. Thought about it for the night and the next day i swapped out the GM HEI 4-pin i used. Looks like i used one i pulled from the bone yard to set it up, but had a new one in the box. Hooked it up, drove the hell out of it. Plugs are clean and like new. I must have gave it a good work out. Sprung a leak in the 4 core radiator. Then spent the next day swapping in and fabbing up another new 4 core.

Thank you guys for the tips and areas i needed to focus on. When you stand for hours in your garage alone, its nice to bounce ideas off someone to make sure you are on the right track.

Good to hear that it's all sorted out.
