I will never run a Zoom clutch again. I bought one for my 340 Dart. Resurfaced the flywheel and installed the clutch. Took it easy for the first few miles. Then when I brought the rpm's up I couldn't push the clutch pedal in. It was like something was preventing it from releasing. Called Summit and they were great. Sent another one right out without me sending back this one first. Well I put the other one in and guess what. Same thing. This time I bent the Z-bar ball lever on the bell-housing. Called Zoom. They have no clue. Told Summit I don't want another Zoom. I got a Ram setup. This works great. I will buy another Ram. Very happy with this setup. These were all Borg & Beck clutches. Zoom wanted me to try there diaphragm clutch but I wanted to stay with the Borg & Beck to keep my left leg muscular. What are the chances of getting two bad clutches in a row. I'm happy with the Ram setup. I don't know if this was a fluke or what. But no Zoom clutches for me.
