Pat's at it again

I'd guestimate:

3-5
5-7
5-8

So, 178 - 185 conceivable CHP, if you are at sea level, the car is in tune, and your compression is solid.

Thanks DLC.. I knew it wasn't a real noticeable amount, but I guess it all adds up, it's more of the fact of the incredible sound it makes when together that sold me.
