I've had a blown 340 Volare Road Runner for years. 7.9-1, 240@.050 cam, small worn out GMC 6V, home ported factory heads, decent converter. It's not a rocket, but is very good on the street. WAy more power than the drag radials can handle without spin. Runs 11.0@122 in street trim. Biggest issue is it's heavy, 3875 lbs. The racecar is a 580" which is much quicker. But also much more radical.
