I pulled my 2.76 SG chunk from a c-body rear. I love it with the 360 in the cuda

If a 440 needs 3.55s for hills you must have a puny, almost dead 440, you need a tune up or something, my 360 pulls up the going to the sun road in glacier national park in 3rd like no ones buisness, very steep and fairly high elevation, breath takeing road.
