I am pretty sure you would net a couple hp less, but they are supposedly 1-3/4" primaries which is good for power. I think that it would make a bit more difference in tq than hp though for the mids vs longtubes. Still think that the lapoles would be worlds better than shortys for power, and they look good quality, and would probably last a while. I do wish that we had a good mid vs long dyno.
