The math will contradict this but the B actually *feels* faster in a stock rig. Something about the power curve I guess. I'm pretty sure it will lose in a race with a 3B powered rig but if you drive them one at a time the B will seem faster. This has been my experience anyway.
You can't really lose on an $800 rig anyway. drive it around while you fix the body and then swap in a 13BT later
My folks live just across the lake from you guys and I'm surprised there's a cruiser in NW Ontario I don't know about. I'll have to have a chat with my spies there.
