Ok, on the front, air horn it's called, there will be numbers. Go to Holley.com, and look up that carb, by the numbers. Then, there will be a parts list for that carb. You can then get the correct part you need.

Thanks for the info I'm going to look it up, also my mechanic put the average metal accelerator pump cam on my throttle in the first position. https://www.youtube.com/watch?v=k-Nx5HEzvlY&t=323s According to this video, cams should be placed in the second position if the idle is higher (mine is around 900-1000 rpms) in order to make the pump kick in later in the rpms? I'm not sure if it would make a difference with the double pumper though.

And its a Holley 600 Double Pump & it says its suppose to have two 50cc

Also, I notice that it bogs down at lower RPM's, this could be partly because it doesnt have the second arm. Do you thin kit could be as a result of the accelerator pump size?

Unless a race application 50 cc pumps are not needed IMHO. If you had the best guy in your area rebuild the carb, I'd say he leaves a lot to be desired. If your spark plug wires say "Accell Super Stock" they are TOTAL junk and need to be replaced, I'd suggest Taylor spiral core.

with the engine OFF and the breather off open the throttle about 1/4 to 1/2 inch .. fuel should shoot from the squirter nozzle the instant you move the throttle .

I think you should maybe move to another city

BAHAHAHA!

I would guess the entire carb....assembled....ended up in a glass bead cabinet. Poor metering blocks full of little glass bb's....sigh.

50cc are installed on holley dominators...that should tell you their purpose. On a street car like this, a vacuum secondary carb would be ideal. Thinking 600cfm.

yeah the car is rough but do you think its worth a swap to c1500?

and yeah it has an accel distrib too lol whats a better distributor for a good price

Hard to beat a stock HEI.

There is a lot of hate toward accel products, but for the street, if it's working then it's probably fine.

I once replaced an accel dizzy on the prejudiced opinion of a local mechanic and it wasn't at all the problem. (Problem was a combination of stall speed, manifold, and carb size.)

Personally I like to keep an extra dizzy module in the glove box, regardless of what brand name the dizzy has.

My headers are loud asf i have a mild cam what would be a good gasket to buy, and would it be a lot more cost efficient to replace them myself?
