1970 Automatic 442 carb question?

I have a 1970 442 that is a CA original car and my carb inlet fitting is pretty messed up so I would like to replace the carb with another carb that would match the car. Am I correct in assuming I would need one with the following numbers? 704055 with a 0,2,4,6, or 8 at the end? If anyone has one let me know.

Thanks

The correct carburetor for a 70 442 automatic is 7040257.If you have the original carb,this should be what you have,or possibily a 7040251. The carb inlet threads can be fixed,so don't give up on it yet.

The original carb on mine car has had it's inlet threads fixed and, if the original owner didn't tell me, I would've never known. It did require disassembling and sending the 'body' out to be done but, for me, well worth it to keep it #s matching and correct. WAY less expensive than a replacement carb too.

May I ask who fixed your inlet?

My local shop screwed it up pretty good. They put some kind of a threaded nipple in it, which of course they didn't put in straight and used some kind of a seal so it wouldn't leak (possibly RTV). They then just used a rubber fuel line and hose clamps to connect it to the metal fuel line. I don't even have the original inlet fitting anymore, and of course I would need a new metal fuel line since they cut the end off of this one.

The guy I bought the car from had the repair done and simply told me he had to send it out (I think he said Texas somewhere). Anyway, I believe they overbored it and installed a helicoil but the factory fuel line installed perfectly with no real evidence of a repair.

Yes---as already mentioned it can be "helicoiled". One place you could contact is Jim McGowan at The Quad Shop. Surely, plenty of others do this also so you could also try that guy up in Wisconsin (Sparky's Carbs or something like that) or others that offer "restoration services" on Quadrajets.

The repair itself isn't cheap....at least $50-60 from what I remember...but worth it if it's the right (and original) carb for the car.

McGowan probably isn't the cheapest guy out there when it comes to restoring and repairing these carbs so check around. For all I know he may not even offer the repair service as a standalone deal....you'll have to contact him and find out.

Someone on here should also have info on that Sparky guy.
