I need a float for my Quadrajet, but I'd like to get the best one I can for it, maybe one that's not as large and will allow more fuel in the bowl.
It's a 1980 model. I used to have a web page that gave me pointers on it but I lost it when my former computer crashed. Any recommendations?

That sucks your computer crashed. I been using the larger floats with the larger needle and seat. Had problems with most of the Edeljunk Q jet 0.149, without an elaborate regulator ect. so i get the 0.145 from Quadrajetparts.com and only ones ever given me trouble (had a rough spot down in there), otherwise good luck with nice flow windows in them. They got all pictures of floats i guess what i want if thy are long arm or not.

Some guys will carve on the float to remove material and this supposedly will add potential volume to the float bowl- but the float has to be resealed so it doesn't soak up fuel and the sealer can outweigh the material removed very quickly. And a sealed float will not last as long as one left alone.

Honestly, IMHO the "best" one for it is a name brand unmodified float made for the exact carb it's going into. As long as the fuel pressure and volume are sufficient the bowl will not be too small until you are into the 500 HP range. If you want, you can use a brass float, the nitrophyl floats will degrade over time w/the sorry fuel we now get. Also be sure there are no nicks or damage to the plastic float before you walk out of the store w/it.

I would have to agree actually on th the float as that has been my experience, trying to go with a smaller float made things terrible to deal with. And I went to larger needle and seat because I had surge problems on my 383 accelerating. That fixed it. It wasn't quite 500 hp, but close wise to how it ran. I also recommend looking at the needle and seat surfaces for no marring or deformity of any kind. Blindly installing these parts may result in your carb running rich or swimming in fuel

I was able to find that Napa carries the identical float I have
so I'm just gonna get it. However I remember the last time I
bought a new float, I think it was $5 bucks, now it's
$15.
