don't hold your breath, and if someone says there is a huge difference ask for time slips, not seat of the pants, like when my car is faster after I wash it. dyno says 10hp, and I say .1 second in the 1/4 mile = 10hp - not worth $1000 where I come from. and my 11 second 360 has 1 3/4" Hookers that cost $350 in 1985
