....on my GT. Got tired of tinkering with the damn thing to get it right....now I'm no expert, so with better skills I'm sure someone could have made the carb right, but I've moved on.

So, now that I have it up and running, this Keith Craft 482FE is an even more amazing beast!!! Throttle response is simply perfect. More seat of the pants power and tires spinning where they didn't before...better be careful.
It took me a couple of days to get it installed and working...was pretty easy, just time consuming. I did have some issues as my O2 sensor is at the end of my pipes, so at and slightly above idle, fresh air would draw in enough to make the system think I was running lean, so it dumped fuel. Call to the Holley tech and the told me to take it out of closed loop until 1200 rpm's and just manually adjust the base idle fuel map which was pretty close to begin with. Then just drive it around and it learns along the way. Runs great!
Now I know this kills the original thing, but it looks like a carb and the wire harness blends fairly well. Overall, I'm happy to have the carb a thing of the past for this car, and it nicely controls my cooling fans independently with separate on/off temps.
