snowfighter Posted August 12, 2016 Share Posted August 12, 2016 Just purchased 1950 Chevy, it has a rebuilt 350. When rebuild it had a manual transmission, every thing worked fine, owner then installed rebuilt a new 350 turbo automatic with stall converter, now it has a vibration up to about 40mph then goes away, new drive shaft was manufactured at fabricating shop, also has 1973 chevelle wagon rearend, thinks 3.5 . Any idea's were the problem maybe? Link to comment Share on other sites More sharing options...
Marty Roth Posted August 15, 2016 Share Posted August 15, 2016 maybe in the torque converter? Link to comment Share on other sites More sharing options...
snowfighter Posted August 15, 2016 Author Share Posted August 15, 2016 New turbo 350 transmission not that one might get a lemon. After researching I think it may be the rear axle angle to transmission out put, got a magnetic angle finder today go to do some checking tomorrow Link to comment Share on other sites More sharing options...
