I here ya brother, I have 10 grand into my custom built 418 and I don't think I'm done yet. It took 4 months and change to get it back. Just ordered another $1000 worth of parts that will be arriving today. I totally feel your pain. Also like jpar said I will have to make suspension modifications to handle it all. I have superstock springs and a pinion snubber but I know I'm gonna need Caltracs or Slide-A-Links if I want to get it all to the ground. Spent so much on the engine that suspension will have to wait. Guess I will have to have a light right foot. Good luck to you.
