Ran my rb25 with a 3.6 I believe it was. Didn't like it so much. The acceleration just wasn't there. So I set that diff aside and picked up a 4.3 and I just love it. I cannot wait till I get tuned so I can really feel the power. I cruise at 3500rpm in 5th and doing 60 but I am positive my rpm's are off 1000(+/-100).
