/6 rebuild advice

That sounds nice! The cam definitely elevates the /6's game.
The only thing about the slant 6 is, it will never be a V8. You can turbo it, blow it, nitrous it, but it will never be a V8. That said, there are some record breakers out there, but they are some NASTY little engines and not "real" streetable. Slant 6 guys build them for the love of the engine and to be different. I can tell you FIRST HAND who gets the most looks at our local cruise ins. I do. I kinda like it. When they hear us pull in the parking lot, they caint believe it's a six when they see under the hood. Here's mine.
