318>383 swap ('74 Valiant)
My sons Dart you see here was a 318 AC car. We had a BB K-frame and used it but now you can get the Schumacher mounts. It really wasn't that bad. Once you have the BB trans and the right eng mounts. We use all the 318 suspension parts (but we rebuilt the front end) including it still has the original 318 torsion bars. I figured we removed the AC and use headers and aluminum intake so it really is not much heavier. It has all the stock body parts and the springs are not moved and it has not been tubbed. You will like the bigblock A-body. His handles great and gets driven everywhere. And it's a mild 400 that runs mid 11's all day.
Oh and don't worry he spanked that ZO6 Vette good. Ron
