Street Gear Poll
Cool stories guys I love reading these...
You can see what I voted for from my sig. I'm also running 275/60-15's. I currently have 2.94s in there and it's actually not bad since my 360 has 10.5:1 compression and a small 213/220* @ .050" cam. I like driving my Duster on the highway and when I put in a 4.10-gear chunk to test out it made me hate driving it anywhere but the drag strip since I couldn't floor it off the line on the street without becoming a cop magnet. With the 2.94s, with 1" torsion bars up front it's really solid and planted at high speeds, 120 MPH isn't unstable in the slightest.
The engine really needs a bigger cam (pings a bit) and I have lying around a "mystery" 2500-stall converter which I tried before but thought the slippage was killing gas mileage (it wasn't). My plan is to get another 3rd member with 3.55s and sure-grip to use most of the time and keep the current one for when I want to go on the occasional long-distance road trip.
You didn't mention what kind of rear end you have, if it's an 8 3/4" having multiple 3rd members is the way to go. 2.94s for the highway, 3.91s for punch on the street or strip.
