Don't read if you're close minded

Ohh definitely the thread long since exhausted the original intent.

My thoughts on the original question....

I think the most obvious possible solution probably is the solution.
1. It's likely that the dominator 1050 flows more than the 4150 based 1050.
2. It's likely that the dominator has better fuel mixing and atomization characteristics.

Without a MAP and intake temp sensor on place it's really guesswork. I will also say...damn it must be nice to get those kind of power numbers out of a dual plane small block.
