103 miles on it. The shift feel is still great though a bit tighter than any other manual trans that I have driven. I've only stalled it once and the Wife was in the car to see that. Driving on the freeway at 80 doing 2200-2300 rpms is great!
I weighed the car this morning. I didn't have the spare tire in the trunk so I'd need to weigh one and add that number to the total.
About 20 years ago, I weighed the car with the original 318-904-8.25 axle but with the Dart front disc brakes. 2 gallons of gas in it and it weighed 3660. A year later with the 440-727-8.75 and I was at 3751, again with 2 gallons of gas. The 440 swap gained only 89 lbs partly because I removed all the underhood A/C stuff.
A couple of years ago before changing the HVAC system, I weighed 3940. This is with frame connectors, torque boxes, bigger torsion bars, front and rear sway bars, extensive sound deadener, the 18" wheels and tires BUT with lighter front seats and lighter rear disc brakes. THIS time I had a full tank.
After the Classic Auto Air project, I was at an even 4000 lbs. This surprised me because the original under dash unit is double the size and weigh as the aftermarket unit and I switched to an aluminum water pump housing. It surprised me to see that I gained 60 lbs despite losing weight elsewhere.
Todays weight with the full tank but NO spare: 3980. What does a spare tire weigh? 40-50 lbs? I guess I'll weigh one and report back.
I thought that this swap could have resulted in a weight reduction until I started looking at the flywheel, clutch and pressure plate. The transmission itself weighs less than the 727. The drive shaft is 5 lbs heavier. This new carpet is heavier.
The 3660 and 3751 numbers are a bit deceptive. To compare to today's numbers, I have to add 17 gallons worth of gasoline weight. Gas weighs approx 6 lbs per gallon so I add 102 lbs to the totals.
3660= 3762
3751=3853.
When I went and learned the 3940 number in early 2018, I was surprised to see that it was so heavy. The difference in gasoline weight makes a big difference.
