Carburetor questions

Well for starters chebbies don't have a KD system.And I think they are engineered for a rear-pulling return spring.And IIRC they are a little taller. And of course you will need to fab up a new fuel-line, and then you have to deal with the chebbie jetting, unless you don't mind being chebbie slow.....lol
When you go to do the fuel-line you will probably find that you will also need the chebbie air cleaner.Which, as you may know, are designed to mute the the secondary roar, at the expense of WOT tire-frying hp. So if your MOPAR turns into a chebel, now you know why.
All kidding aside, Spreadbores are the best.
