Holley choke question

[Hemi Mike]

I was using a Holley 600vac. #1850 on a warmed over 360ci. Since I was somewhat concerned with MPG and driveability I thought this was the right choice. Man was I wrong. The 600 was running lean so I was going to jet it up when I spotted this old 750vac. #3310 hanging on my garage wall. Got a BG rebuild kit and this thing is awsome! Way better power, throttle responce and probably MPG.

I am having one little problem though. The 600 has an electric choke that uses an internal vacuum source. The 750 has no provision for it that I know of. Can I swap this ckoke over to the 3310? I know Holley sells a different choke for each aplication (int,ext vac. source).

As far as I know the 3310 has the vacuum port you need for the choke. My freind ordered one for his 3310. I found the port on the side and it had vacuum. The port you need might have a screw in it right now. Take off everything ahead of the vacuum diaphram for the secondaries. One of the tapped holes should have vacuum.
