Re: Another member of the 415 club
Thanks.
Driving impressions: The car has been transformed. Most of my driving has been at highway speeds. With the 3.90 rear and increased torque, I can easily cruise in 6th gear. 2000 rpm at 75mph. There is enough torque to accelerate from 55mph without downshifting. Cruise control has no problem keeping speed on steeper inclines. After about 400 miles, averaging 19mpg. 1st gear is very useable, especially in traffic. I don't have to slip the clutch as before the gear swap. Coilovers we're chosen to be 10% softer than stock. Car no longer "skips" across bumpy roads. Very comfortable and stable. The springs lowered the height by about 1". Perfect stance. Overall. I'm real happy with the end result.

Re: Another member of the 415 club
What did it cost for the motor work and putting in 3.90 gears?

Prices for the work are on Marc Haibeck's website. I'll just say it was more than I paid for the car.
