Conversation Between 96capricemgr and 1963SS

Good morning, I followed your recommendation on the AFR valve springs. Their great and the car runs great except...........the transmission shift fine, the 3600 converter is a blast but when the torque converter locks the car shudders a lot. In my 69 years I've never seen one this bad. I'm off on the Hot Rod Power Tour with my nephew in 10 days and was wondering how to correct this. The cam isn't real smooth at 2000 RPM and I know that's part of my problem. I have a 242/248 cam with almost .600 lift on a 112 CL.

I've heard that your car runs great and was wondering who did the tuning. My converter locks up at 45 MPH right now but I've had it out on the Interstate and it is still a bit rough at 70. (2300 RPM) I have 3.73 gears. When I say it shudders (cam surge, whatever) it feels like it will take the U-joints out in the first 100 miles. It's that violent. Any help would be appreciated. Thanks. ---Gunny---
