transmission from an Oldsmobile 305? The old engine (Olds 305) needs work, and I would like to have a better engine in the car. What I am concered about is whether the LT-1 will bolt onto the existing TH700 or 800 transmission without major modifcations. I have a 96 Impala SS with a LT-1, and the performance of the car obviously is great. I do not plan on using the wagon for towing or heavy hauling, but want to "spiff" up the car, as the rest of it is in excellent shape.
