Edelbrock LD4B - what's the operating range?
for that particular application a performer, the LD or a stock TQ intake are all going to be comparable. i'd probably push toward headers to pick up a little more low end and midrange torque as well as cost considerations, but you wouldn't be losing much at all with 340 manifolds.
i like that combo and the addition of a OD lockup with some gears out back should really make it shine all around.
