Thanks for all of your help. I am running a stock 350 engine with a rearend that has around 3.40 gears( I'm not sure of the exact number). I think that I am gonna go with the turbo 350 because the guy who is building the transmission said that he could provide the core and the rebuild for 360 dollars and that the performance would be just fine. My major concern is running at high RPMs when I get on the interstate because it is going to be a daily driver not a hot rod. So I guess gas mileage will be a concern also(when is it not these days). He also said that it could be a bit tricky getting everything hooked up where it would shift just right and I could run the risk of burning it up. I really have no idea what he is talking about there but I guess I've got to trust him. After all he is the professional not me. Thanks again for everyone's help. If someone who has a 64-66 chevy pickup with a 350/350 driveline could let me know how it is working for them I would greatly appreciate. Thanks again
