For a street truck, either will do a fine job. I give the nod at the track to the long bars IMO. But most won't go fast enough to know any different. A good set of double adjustable rear shocks are more important I think. They made me a believer after going 1.31 in the 60' with a radial on my dad's truck. Standard long bars with double adjustable rear shocks and single fronts. Whole lotta power.
