If it runs that strong, I hope you will be very careful getting used to it. I went from a mid 11 second street car to a 10 second car and there was a bit of a learning curve there, especially when jumping into it on public streets. I finally went to MT ET streets because if you hit it just a bit to hard to pass, it would get loose. This is not meant to be condescending in any way, and I am sure that is what Brad is getting at. As far as a carb goes, I think any of the quality carbs mentioned in a 950 would balance your need for power and streetability. You could always get a larger carb later, if needed. You have to find a balance for your expectations. I built a nice 493 for a friend with a Holley HP 950 and he loves it as he drives it on the street 99% of the time. Lots of good advice here and good luck!
