1992 Dodge Dakota 5.2 Magnum advice
AJ, my memory fails, what's the OD ratio of the A-500? Which he more than likely has in a Dakota truck. .68?
Magnumdakota, multiple the OD ratio by the rear gear ratio for the final drive feel.
4.30 X .68 = 2.92. Still a very friendly street and Hwy. gear.
You know it!
And with 235/75-15s being about 29 tall, they correct the 3.91s to 3.91x 24/29=
3.24s with 24s . Now very few people run 24s. Typically we run something like 25.5s, which would correct 3.55s(also typical) to 3.55 x 24/25.5=
3.34s. So 3.34-corrected is a typical target when an O/D is not available.
Now as to OPs combo, compare those 29s and with 4.30s; 4.30x 24/29=
3.56s.
Another option for the OP is much smaller tires, say 275/50-15s which are 25.8s, which correct to 3.91x 24/25.8=
3.64s. Which compares very favorably to the 4.30 x 29s @ 3.56. Of course the front tires would also have to be changed. And then there's the rather odd appearance of a Dak on small tires........ but hey, if you can borrow a pair of 24s or 25s for a test run......let the fun begin!
My son had an 84 D100. I put my winter-motor, a stock 1973 318 into it with the TQ on it and stock exhaust. And we put 3.55s into it, a 2800TC and an A998 with the 2.74 low gear in it. Then we put my used 275/50-15s on it. That truck had a whole new personality. The starter was 2.74 x3.55=9.73 and corrected to 24s this is a 9.05 starter.( This compares to 9.05/2.45= 3.69s with a 2.45 low, and would require 4.46s in the Dak with 29s to compare). I had to fab a traction aider cuz with the 2800, and the TQ set on stun, those 275s just couldn't take it.Top of first was about 40 mph.
The OPs Dak with a 4.30 x2.45low and 29s corrects to 8.73; within 4% of our D100 with it's 9.05 corrected starter. Now add in the 2800TC, and let the tire shredding begin.
And remember, that 318 was totally 1973 low-C vintage, except for the TQ, and it was breathing thru the 1984 logs and Y-pipe,lol.
