Its a great manifold for the street.
Maybe a little much for a stock motor, but ideal for something with a small cam and other mild upgrades.

YES! You might lose a little torque right off idle cause of the huge runners but the midrange and topend will pull HARD! If you have gears it will help it rev right through the stall, mine starts at just over 2k and as far as I want to take it. But I also have heads/cam so so my RPM range is higher. I read graphs of these intakes on solid cam race engines making power at 7000+rpm, almost as much as a single plane with a WAY better curve and avg's across the board.
