I have to agree with Rex,The Super E is a great carb.I put one on my 83 and it worked great . throttle response,acceleration and cold start ups all were better.Because it's much larger than stock,You'll notice how much less you need to turn the throttle too.Very simple tuning and your on your way.I kicked around the idea of a 90's CV carb,which alot of guys like ( can be reworked for race)and will work good but,it still ain't no S&S!Do yourself a favor and bite the bullet for a $325.00 S&S kit!
