I gotcha - that makes sense. They were just so similar that I wanted to try to hit the nail on the head. I suppose I should have looked at your sig... lol.

I thought about building a roller 400 before I built my BBC... Then I found such a killer deal on a nearly virgin 454 block that I couldnt turn it down. What are your plans with it to improve on your ET? Or, are you going to just race it as it is?
