Carby no should have been 17059222.

I'm really a motorcycle man and our carby's are very simple devices. Not much better than surface vaporizers to be truthful.

I bought the replacement as a "correct for 1972 350 Corvettes" before I had any idea of what I was really buying. All I knew was the fuel system had a fair amount of rust in it and after installing a new tank I didn't want to have to rebuild the carby before driving the beast. It was barely running.

I'm undecided yet as to keeping the car as original as possible and hving something with a bit more power. Truth is, I'm considering swapping in a crate motor as it's a lot cheaper than rebuilding the original.

But I am impressed with the Quadrajet as a carby. So much more sophisticated than a Super B (S&S). As I said the carb I bought as a replacement works reasonably well out of the box. I presume I could tweak it and get it just right.

Part of what I'm doing is just "tinkering". I build my own motorcycle race engines and just like playing with this stuff. If I did decide to swap out the engine I would keep the original engine to stay with the car. Someone down the track might just prefer an all numbers matching car.

I've seen a couple of 7042202 cores but they're asking upwards of $200 for them. I wouldn't have thought they were worth that considering there are so many equivalents around for under $50.

But I supposew if I'm going to spend time and money on one it should ne correct for my car.

The Corvette won't see high milage so would the inferior interior parts prove to be much of a problem in the short run ?

Also, Cliff says in the book that "the later carbs, post 1976 are actually better". So I thought the 17059222 would be a better bet ?

 It's alright. I have been called worse. ;D

 I would go with the 17059222. It will probably take some modifications. Cliff will know more on that.
