69 Dart 4 door cruiser
I'm a bit unsure on how I'm going to proceed with the transmission and rear axle. I welcome suggestions but please don't be offended if I don't choose what you suggest! I will consider what is posted here.
The 360 that I'm going to use is going to get cleaned up and resealed with new oil pan gaskets and valve cover gaskets.
I have two transmissions that I can use. One is a 1988 904/999 with the low 1st and 2nd gear.
The second is an A-500 that has the same ratios as the 998 but also a .69 overdrive ratio.
The 8 1/4" axle has a Sure Grip differential but 2.71 gears. I have a set of 3.21 gears that I can use, a FABO member has a set of 3.92s for a fair price.
* I figure that IF I used the 999, I'd stick with the 3.21 Sure Grip. This would mean acceleration in 1st similar to a 3.55 with a standard 904 and a final drive of 3.21. Not bad.
* If I used the A-500, it would involve cutting of the floor and transmission crossmember. There are also wiring issues to get the overdrive and lockup clutch to work.
I'm up for the challenge but I'm weighing the value of the effort. I'd use the 3.92 gears if I used this transmission. The final drive would then be 2.70.
I don't know how long I'll keep this car. I've gone back and forth on whether I'd build it and enjoy it for a few years or just sell it not long after I am done. Like many of you, I have a few ongoing projects and as much as I like the car, I have others that I like a bit more.
I'm tempted to go the easy route and use the 999 and 3.21 gears. Let me know what you think!
