    It was for a little while, I had a check ball issue in the forward drum; totally melted the clutches/steels. It’s been down for upgrades for too long. Best it ran on 10# was a 7.00 1/8th @97 mph street testing.
    upgrading the TH400 to 6-6-4 clutches, steel forward hub, JEGS trans-brake and a 10” PTC specs by Dusty Bradford to work with my 2.73 gears. It’s setup to run 1/8 on the street using 1st and 2nd similar to a PG.
    If I wanted to switch over and maximize the 1/4 mile he recommended changing to a 3.73-4.10 to better use 3rd gear.
