Stock 340 Manifolds or TTI Shorties?
Maybe a little, but no "wow" difference. Engine pulls strong through about 5500. Started the new engine with the 670 street avenger I had and just put the 750 on that came with the engine. That carb seems to have better idle and low speed manners. Tell you what, when that 3000 stall converter brings the power to the wheels, it is awesome! Car is really fun to drive now. Think it runs better than the 440 I built years ago in a lighter weight package. Win-win in my opinion!
