Carb Kit for 72 302 2BBL

Where can I get a kit online and even better jets?

I guess this is a 2100 (original carb)?

I saw some kits on ebay, but I would think that there are some sites that specialize in this sort of thing.

 

What do you mean by "better jets" ?

 

Larger sizes.
Can the mains be changed in a 2300?

 

You mean a 2100 ? A 2300 is a Holley carb. And yes both have removeable jets. But don't think you can "jet up" or "Jet down" a carb to increase or decrease the cfm rating (make it a bigger or smaller carb) It doesn't work that way. The jets serve to regulate the mixture, not the cfm rating. 2100/4100's have pysically larger jets, I'm not sure they're interchangeable with Holley jets. Try "Pony Carbs" for replacement jets for a 2100/4100

 

Sorry for the confusion.
I am looking for a Holley 2300 but I have a 2100. I have found a cheap 2300 and I am going to buy it and rebuild it also.
I did find the rebuild kit for the 2100 at Orielly's. I was suprised at how readily available the parts are.

I realize you cannot change the CFM rating with jetting but you should be able to make minor ajustments to fuel/air ratio correct?

I do plan on a torker manifold and a 600CFM Holley when I rebuild or put another motor in. That motor would not be entirely stock though.

Thanks for the reference for jets, I will look them up.

 

Yes,that is correct on the air/fuel ratio. I just wanted to be sure you were clear on jetting and the changes it makes. I run across many guys who thought that you could jet up or down a carb to make it flow more cfm's. You going with a 350 or a 500 cfm 2300? The 500 is an inexpensive way to 4 bbl performance in a 2 bbl package.

 

I was looking at the 350's but I will keep my eyes peeled for a 500. Yeah, that would be great, did not know that. You guy's are a great resource.

I am not as concerned as much with the performance on my old motor as it is about to rollover the odometer. I am just wanting it to run clean and well and last a little longer. It seems to be in pretty good condition for the mileage and being all orig.

When I build up a motor I will change the manifold and carb to something that flows better and the motor should appreciate the extra CFM. I am hoping to do this in 1 1/2 to 2 years from now (motor build).
