For your car i would go with 3.73's. Assuming you have 3.23's now it would be a nice improvement. JMO

I think the only hesitation I have is it is a street car and I have ran 150+ mph before does that matter

I pulled mine on the freeway last week to 140+ only reason I got out of it I was approaching traffic. I don't recall where my rpm was beacuse I was watching my AFR gauge.
