1st off no 350 car came with a 5 speed from the factory, so i think you mightta been dooped.

2nd, why does everyone think octane = speed? It probably slowed you down. All octane means is resistance to knock, in theory for the most power you want to run the lowest octane possible without detonating.

But yea, are you sure all 8 cylinders were firing?

Also, 60' is important, and if you werent spinning with street tires, stickier ones arent going to make much of a difference.
What was your 1/4 mph? I would assume mid 80s with that kind of ET.

Your car may have some basic mechanical issues, post up whats done to the car, mileage, etc...and I'm sure everyone will have 46 tips of what you can do to improve. It wont take much to do that I can assure you.

beings its a 5 speed, I'm sure there is a lot of room for improvement just in driving, and the resident memphis raines' on the board will be sure to tell you how!
