I’m looking for an engine for an '81 Ford truck. I really want a 302 or a 351, nothing bigger than a 408. I currently have a 300 I6 but there is a rod knock. It has a 3 speed on the floor, but I want to change to a five speed. Now, the five speed would have to be complete. But, I wouldn’t mind it Tue engine was just the block. Feel free to email any pictures and approximate prices. I have a project car and motorcycle. So, I’m not able to offer a lot.
