in too deep: trying to go BBP on a 68 barracuda and its going.. poorly.

First off, if it's going poorly, you're doing it wrong. This has been done and done easily for decades. You should have done research first, instead of after, then you'd be well educated on what to do. These cars aren't Chevys. They're a little different and require a different approach. I second the Dr Diff recommendation. Cass is a great guy. If anyone can help you make chicken salad out of chicken ****, he's your guy. Looks like you have a nice car. Maybe next time you tackle a project on it, you'll do your research first. It might save you a lot of trouble.
