Yes, on that manifold, there is no technical reason to plug off the empty choke well if the divorced choke spring assembly is removed.

Really? Should the motor be revved with the outboard rods disconnected high enough to open the outboards via the vacuum signal there will be nothing to close them mechanically quickly. There is potential for an unloaded out of control full throttle event, "engine damage may result".

You are describing the outboard closure linkage/rods. Yes, need to set the center carb curb idle, or with an idle solenoid low curb idle, with the rods disconnected first. BTW, when disconnecting the rods, disconnect the vacuum hose that opens the outboards as well. Never run the motor with the...

Click "Watch on Youtube" in the video, check the comments, I answered a comment about specific parts needed the other day. Yes, you will need a six-pack divorced choke to begin with and a later ('73 and up) heated divorced choke spring. "The six-pack divorced choke looks to be still available...

There has been some recent renewed interest in a modification I did years ago to incorporate an electrically heat assisted six-pack divorced choke using components from later Chrysler carburetor choke systems. Allows for a fully functional six-pack automatic choke while running a cold intake...

"The Monster"

Frankenstein? Should I be offended? Pretty easy to do actually. The timers are easy to find now premade. I would disagree with those saying this original choke system works correctly without any manifold heat at all. The spring tension of the divorced choke vs engine temperature is specifically...

The hole is indeed related to a hot idle compensator valve system mounted to the back of the center carb if the list number called for it. Otherwise, the needed machine work for the passages, valve and cover would be omitted.

Not sure I’m following the 4150 & 4160 references Bob, these two-barrel carbs are known as 2300 series Holleys, some similar attributes like metering plates. The original 4144 & 4374 California only center carbs used the same bowl as ’71, with the enclosed idle bowl vent valve. Agree, that date...

To answer the original question, yes, the '70 4144 with the enclosed idle bowl vent valve will work fine on the ’71 three nipple breather ECS system. No major functional difference between the ’70 California only N95 and the ’71 all federal N95 ECS systems.

The ’69 FSM shows a bore size of 1-9/16” for both primary and secondary, primary venturi at 1-1/4”, secondary venturi at 1-5/16”. I’m going to say closer to 600CFM for the 4166 on the standard performance 440 application. I’ve spent many hours back in the day digging through Holey parts...

See post #17, running a pair reproduction 3/8” hard lines on my ’72 SS. If it’s an early ’72 (before April ’72) you can run the recently released ’71 fuel tank designed for an in-tank pump. Use your existing single line. Keep in mind that car should have a 5/16” main fuel line, most EFI want as...

The cut-over was April 1, ’72, Spectra CR10A (vent nipples on drivers side, same as ’71) and Spectra CR10B (nipples on the front of the tank, also used for '73). The early wheel well mounted fuel tank vapor separator was prone to rust caused pin holes due to heavy water exposure in the wheel...

I can guess, there is quite a bit of information presented in Uncle Tony’s video to disagree with IMO. Using a ECS fuel tank vent line as a return line? There is a reason the factory ran a separate return line on factory installed fuel pump vapor separator installations.

Not correct, perhaps you should have a looked at the factory service manuals from ’70-71, relating to the Evaporation Control System, it's function and the correct information on the fuel bowl vent valve hose routing. Called Holley? Did you ask them why the current re-issues of the ’71 center...

Nothing to disagree with in the first sentence of that post about low performance 440 OE Holley’s, including the reference to low quality, didn't see a reason to quote it. Only taking issue with the comment about 440 HPs never having run Holley OE carbs, no specific to model year range...

With one model year exception, nothing but Holley 4160s on 1972 440 HPs.

The OP specified a manual transmission, had it been coded for N96, R-6193A would be the correct original list number. List number R-4735A is N96 automatic transmission only.

6193 is for fresh air (Air Grabber), not seeing it coded for N96

‘71 383 HP 4-speed, heated air(not seeing N96 on the tag), would have left the factory with a Holley 4160 List number R-6191A. Holley R-4668A is the list number for heated air/auto trans.
