Sorry to hear your hemi deal was a flop. Keep your eyes open though and something will turn up if you're patient.
In answer to your question, you can put a carb on these engines and run the ignition with an MSD Hemi-6 controller. You can get a single 4 bbl intake from XV Motorsports for about $600 IF they have them in stock! You can also get an Edelbrock dual 4 intake from Summit or Jegs for about $450 or a modular intake with the top of your choice (single 4, dual 4 or six pack) from Indy for about $600. Forget about the Mopar Performance single 4 bbl intake, they are WAY overpriced at more than $1,000! The MSD Hemi-6 controller will run about $700 with the correct wire harness for your application from either Jegs ore Summit.
This is the way I installed mine, and it works great! If you want more details on my install just ask away!
