2 barrel , 4 barrel, whose got the answer?

I managed to convert a two barrel kickdown linkage to the Holley 4150 on my 318 car back when I was only 18. It's not too hard to do if you have a bit of mechanical knowhow.

The hardest part in my opinion is properly hooking up your throttle cable. You tend to have to clamp it the cable into the bracket on the sleeve, which tends to cause problems. That being said, my 71 Satellite Sebring has been driven like that for the past 6 years and hasn't broken the cable yet.
