26% with what you have. I have that in a roadster with a 3:54 diff. Works as the car is so light. Mitchell told me that the ideal was 4:11 with the 36. I have the 36% B/W in a coupe with the 3:78. That will not be the car I take to Sparks. It is okay on occasional hills, but from the Bay area to Spark is almost 8K feet climb on the route we take, Hwy 88. That is too much for my engine. I had a 3:78 and 36% B/W in a ccpu with Cragar overhead. That worked will over the mountains from here to Portland and back. IMHO your choice should be the 26%. Great product, you'll like it.
