There are no easy answers here. "What will work best" and "what is least expensive for a college student" are probably mutually exclusive. Understand that a Chevy 350 was not designed to fit into a CJ-7, nor was the CJ-7 designed to accept the 350. There are dozens of decisions to be made, and issues to be addressed, before parts fit together properly, line up, and work without breaking. A good place to start is the Advance Adapters Jeep Technical Manual ($10.00) and Buyer's Guide (free). Both are available at

These do not address all the issues that you will encounter, nor is Advance Adapters the only place to buy the parts that you will need, but they do give a fairly realistic picture of what will be required.

What you propose to do requires a considerable amount of knowledge and expertise, comparable to what you would get from two or three advanced level college courses. Do not expect to get that knowledge for free, or without effort. There are people here too, who will tell you things that are wrong, or that are not appropriate for your needs. It just makes things more interesting.

Ja, but this kid thinks he's getting a bargain with a "free" 350.

He can also get a buddies '79 I-6. Wouldn't that just swap in?

It doesn't mention the condition of the buddies I-6 but some repairs have to be cheaper and faster than the Chevy 350 installation.

Same block for the 304 and the 401, no?

Folks that I knew that 304s reported that they could _see_ the gas gage dropping as they drove.

You reminded me of the old Ford VV (variable venturi) carbs. What a nightmare they were.

A friend's grandfather stacked carburetor adapters from J. C. Whitney on the intake manifold of his Chrysler Imperial, and got more than 20 mpg from a one barrel carburetor. This was in the early seventies, when the Arabs were first getting kranky about the prices they were being paid for petroleum.

I am told that if I replace the carburetor in my wife's FJ-40 with fuel injection from a 4.3 liter Chevy, I should get that much, and not bad performance either. Seventies era carburetors were pretty bad, as I remember, because they were first starting to be choked with emissions controls, and because fuel was still relatively cheap.
