I have a built 355 LT1. Im running the cc306 cam with 1.6 roller rockers. I have 373 gears. Im putting a 350 lock up transmission in it. I dont have a lock up stall for it. How is the stock convertor going to work. Im running a 3500 stall in my 700r4. What differences will i see for the good or bad.

 

All I can say is be prepared to pop it into neutral at stop lights to keep it from stalling. I don't know exactly what will happen, but I thought about doing that in my LT1 for a little while but people convinced me not to. Why not wait to install the 350 until you can get a converter for it? Sounds like your current tranny is already up to the task with a 3500 stall. Either way good luck and let us know what happens
