Hemi carbs, or big block afb?

I have a 4742/4746 CO 1970 Hemi Carb set for sale. The 4742 is NOS carb and the 4746 has been restored but modified for bigger HP motor. Can have choke blade locked out, vented top without clean air vent hose. Has fatter jets/rods, and uses the HP kit primary venturi. Does not have choke housing...

What is wrong with pump, looks fine. DO NOT lose the pump pulley. It is hemi only for 69-71. Changing to different pump/pulley will cause belt line up issues.

Hose is not correct. At the steering gear should be a 90deg brass fitting so hose attaches horizontally instead of vertically like yours. I am not sure anyone repoped hemi hoses. Anything wrong with yours?

What does that mean? I just want to confirm it is inline. That make a big difference versus Cross ram carbs jetted for a cross ram.

The well choke is set to hold choke valve closed until engine warms up and open the choke valve. More tension on choke valve longer to open and run richer. Less tension opens faster. Normally you leave factory units alone. The Diaphragm is a choke pull off. Since choke is closed to start...

Is this cross ram manifold or marine inline?

Can you provide picture of your hose?

The book say good for 63-77 year. But in 70 the 11" became a scalloped clutch and had to be less than 11". So if it is true 11" it will not work for the 70 up Big Block scalloped pressure plates. That is why a measurement would be useful.

Is the diameter true 11" or smaller.

The Secondary uses a 6-32 5/16" and the Primary a 3/8". They are fillister head screws not flat head. Do need to file peen off to remove and be slow about backing out. Out, then in, file more until come out nice and easy. If they are center punched I do drill the center punch first to remove...

As you are undoing the fp bolts there will be pressure pushing pump off the block if in the stoke position.

If you're just cranking it, is going to pulse. There is a standard volume per minute as a test 1 quart per min at 500 rpm. Vacuum test at inlet of 10" Hg at 500 with line disconnected from carb. Yes to rod. The lever must engage the rod so rod needs to be pushed up against cam (hopefully...

For 66-67 the manual talks about balancing equal. The 68 and up are different carbs and jetting for CAP. It is about getting cylinder distribution right and no misses on front cylinders.

Yep 69 A body 383 4B with Auto

These are OEM correct choke housings in excellent condition. These are used on the 66-67 cars. Would work on later one but would not be correct. If you need original housing because of a missing one or corroded from heat tube failure here they are. Asking $100ea shipping included for USA.

The rods not correct for hemi.

The order number in 67 for CAP was 471. CA only mandatory.

Yes in CAP cars the crankcase ventilation became a closed system and the breather got a nipple to go to air cleaner so any emissions are burned through engine, either at vacuum port from PCV or through air cleaner if venting from cap. Not sure about 66 but 67 hemi/440HP was a chrome valve. As...

Chrysler was able to get the 426 Hemi Exempt from CA emissions for 1966 model year. In 67 all CA cars were CAP. For hemi it meant the 4324/4325 Carburetors and different distributor along with emission valve for 4 speed cars. The primary difference is leaner idle jet in rear carb, and...
