carb question.

[Shane90GT]

I have 2 carbs one is a holley 600cfm vac sec. the other is a holley 650 DP. My combo is a 99 explorer bottem end (stock) Stock gt40p's with spring upgrade and milled .030, TFS stage 1 cam. and a Weiand stealth intake. I am wondering what carb i should use. This is going to be a street/ strip car.

The 600 vac sec should be all you need. It will be especially nice for
street driving. If you tune the DP well it would give you a little more
punch at the track, but your daily gas mileage might suffer.
If you have both, it's not hard to do a quick carb swap. I would set up the
600 for the street and set up the 650 for the track and just swap it when
you need to.

the 600 should be plenty..but like teknik said, they arent hard to change
