Your buddy is recommending a Rochester carb or a Carter. Either are as good as a Holley.
With a 4 speed trans, my recommendation is a Holley 4150 series double pumper carb. You can see them on Holly's website www.holley.com
In my opinion the Holley is easiest to tune, but others opinions may vary.

You think your current Holley is worn out, but unless the throttle shafts are worn there really isn't too much else that can wear out. There are also bushing kits available to repair the throttle shaft bores if that is the case.

What are the symptoms of the car now that make you think there is a carb problem?
