With the 4-speed, it ran a best 1/4 mile of 14.96 at 98.02MPH. The speed is there, but I can't get it to hook up with the 2.73:1 station wagon gears in there. Next order of business is to get a 4.11:1 posi for the car (preferably a 12-bolt), and then I plan to put a Holley 4150 on it. Anyone have any experience with this? I'm not sure if I want to spend the extra $$$ and get a Barry Grant "Gold Claw" or just get a stock 4150.
 

After installing the Barry Grant carburetor and a couple jet changes, I ran the 1/4 mile in 14.10 at 101.8MPH.  The speed was very consistent, much better than the old Edelbrock carb.  I also had to bump up the rev limiter to about 7000RPM so that I could finish the 1/4 in 3rd gear.
