69 barracuda stock 318

I'd agree with everything said here. If you want to hit 11s with a stock long block 318, you're going to need quite a bit of nitrous or forced induction.

I'm running a 10:1 360 in my Duster with OOTB Edelbrock heads and I'm knocking on 11s. I've been within about .10 of 11s and, since I've finally figured out my fuel delivery issue, I'm thinking it'll happen this season.

I'd say the best way to get there easily would be with a stroker, especially if you want to keep your 3.54 gears...but, it comes down to what your budget is.
