Do you have any idea what you are running now? My guess, and its probably a very poor one at that would be low 14's

Your gas mileage will drop, but 1-3/4 will be much better for power on your 350. I assume the rest of your car is bone stock? the 52mm TB may be a bit much for now. Spend the money on a dremel and bits and get a little port crazy.
If you're motor is in perfect shape otherwise (full tuneup, no leaks, running nice and clean) I'd say high 13's *MIGHT* be possible. Don't quote me though. Definately low 14's. That's a MAP motor, right?

yeh... a 52mm would a total waste on money, get a dremel and do some porting, get an air foil, and an AFPR

We could play guessing games all day long, but you'll never be sure till you run it. Making guess like this are very subjective, especially when your trying to evaluate given mods. I could say mid 14's and somebody else might say mid 13's, thats alot of leeway.
If I had to guess, I'd say 13.9

Yea he's totally right because there are so many variables...Its so hard to get the perfect run.... Like right now its colder but if you run in the summer you'll be slower, hook everything....
