A 13.7 @ 100 isn't bad for just a B303 cam, 1.7's, pulleys, exhaust, 3.55's, and good tires. I think your guesstimate of approx. 260 HP is accurate.

The 70mm TB is a little large for your stock intake & heads. I would try a 65mm if you plan to keep them both.

Problem now is that you have a lot of air going in and out of the engine - which is good - but the stock heads can't utilize it efficiently - which is not good. With some tuning and driving practice you might knock off another tenth or so but yeah, you need to upgrade the cylinder heads/intake to see a real et drop.
