Edelbrock Thunder 650 AVS

I just put the Thunder AVS-2 650 on my 68 340 GTS. I'm running the 4 hole spacer on a Performer RPM intake. I can't believe how much smoother the car runs. I took it out of the box put it on set the idle then the fuel air screws then the choke. This carb works perfect. I can actually work in the garage with the car running and not have it burn my eyes. The 650 replaced a eddy 750 that I could never lean it out far enough to get it to run right, always had a very rough idle and very rich when idling. To much snow on the ground yet to take it out on the road to see how she will run.
