I have a 85 Cutlass Supreme. I've owned it for some years and it unfortunately it has been sitting for a while. The current engine in there is a 3.8. Last it ran was years ago and a rod was knocking. I found a used 3.8 motor at a used auto parts spot for $550. Didn't purchase it yet. I've been doing some research and looking at the threads commented on and it seems like placing a 350 SBC would take time, its costly and you have to have the right person do the job. I'm a little up in the air of what to do. If I could get some advice on what to do I would appreciate this feedback.
