Rich Kinsley '64 Dodge Polara 4dr 318poly w/goodies I did the calc's on top speed in my gears and the formulas say I can do 77mph in 2d with the tire/ratio set-up I am using now. I'm turning between 69 and 70. I go thru the traps at or above 6000rpm's according to my cheapy tach. Perhaps it's lying to me? Or there is slippage in the driveline. Anyway I am thinking I should try shifting sooner, like 5000rpm. I did it once last week on my final run and I had a 9.765@xxxxx which was my second best for the night. I don't trust single runs for a definitive answer though. However I do feel I may be holding it too long in each gear so it's kinda tapering off at the top. It does pull real good at the shift. It always chirps strong on the 1-2 shift especially. Any thoughts? ---- Please address private mail -- mail of interest to only one person -- directly to that person.
