Alex,
I know that you're flip flopping on whether to go with the rotary or LT1. As I've voiced before, if it was my car, I would change to V8. I have nothing against rotaries, actually I think that they are sexy as hell, but they are so damned expensive. The price per HP compared to a domestic V8 is astounding, and maintenance may also be an issue. If you are going to have buget constraints in the long run too, think hard about your decisions now.
On the other hand, V8 conversions are becoming a dime a dozen now, so having the uniqueness of the rotary swap is very cool. In the end, do what is going to make you happy....don't take into account what we mutt heads on the board say.........Either way......buy a welder would you!!
My 2c is all spent!!
