6cyl intake swap

I did this to my 74 about a few months ago. i even put a super six setup in it too. I did replace both the exhaust and intake manifolds as a unit but if you take them apart there is a crazy gasket you have to replace. The super six setup was a cool idea but i cant get a good carb so it runs a little rich :( but i did see an increase in power. If you go super you have to upgrade the exhaust system for sure ( 2 1/2 and i chose a Borla muffler for sound) otherwise you wont see much a difference due to the restriction. One bad thing wit the super set up is that i caught hell trying to locate the kickdown linkage for it. Maybe a cable would work better?
