Well, at 50 hp it did well. I think it ran just in the 14s with the warmed over yet very tired 318 on the motor alone. On 50 shot it ran low 14s. It was pumping oil out the breathers pretty well having to wipe up the mess after every pass. We then decide if 50 is good 150 is better! Not so much. It went 2 passes and was hindered by the 3.23 one legger 7 1/4 rear and 205 tires. Traction be damned it went 13 flat! Twice! It smoked really bad even after the run it was smoking pretty bad out the tail pipes and there was oil all over the fire wall. On run 3 it broke several rods in high gear, making a mess out of the car!
