I would not waste my time or money. That old six is never going to wake up like a V8. My advice is to keep it stock until someday you want to change engines.

I am leaning towards a stock set up.

I am still researching on the 4.1 carburetor. Hoping someone who has done thee weber 32/36 38/38 combo chime in and tell the outcome of this setup. Thank You

For about 1,000 bucks, a few hundred more, you can put on a 2bbl FI set.up....Holley Sniper.

There is a cheaper kit.

They also have a 1bbl kit and a Chevy 2bbl style kit.

In my experience, all of this is more show than go. The engine itself was designed to be "adequate" power and while fuel injection will give easier starting and more precise throttle response, I don't see it giving enough additional horsepower to make it worth doing.

I once saw a vehicle that had some kind of custom intake that had 4 4bbl carburetors on a small block engine. There is no way that the engine would ever pull enough air to satisfy all of those carburetors. However, it looked interesting.

On a vehicle of that age, a stock setup will draw more interest than a gizzed up mess.
