Carter WCFB or Rochester 4GC?
 

Which works better for a 283?

Just curious.

My old 250 hp 327" was a good bit faster with a 4GC.

Yes.

Ditto

Especially if you race a stick in stock! Dean Oliver can do wonders with these carbs! The 4gc is a small, but very reliable carb to race with too. We have used them on our 283s and 327 250 hp combos for years. The wcfb was a lot more picky about fuel control on the launch for stocker stick cars anyway.

Thanks guys. That makes it unanimous.

I wonder why Chev chose to go with Carters for their 2 four set-ups (245/270 HP)?

Probably because back then, for them, there was no difference or it was negligible.

When looking for rebuildable cores for either a WCFB or a 4 jet, keep in mind there are different sizes of both. The 265 and 283 up to at least 1961 used a smaller carb than the 64-66 283. The 250 horse 348 used a bigger 4 jet, that was carried over to the 62-65 327 250 horse,and the 64-66 283 as well. A local racer was looking for a WCFB for a '55 he was starting to build,and I had one from a 65 327 that I once owned, (the only part I still have from that car),and it was considerably larger than the 265 unit. The 63-65 340 horse 409 used a large 4 jet,but it differed externally enough to be very obvious. Just be sure you get the right unit. If you plan on racing a 65 327, let's say, and inadvertently got a '60-61 283 carb on it, that could be the reason it's not real fast.
