It is a 1985 with a 502/th400 and 4.11 gears. It went throw a 400 already after 2500 miles ripped the bell off the thing so pulled it out an put a j.w. ultra bell on it with a b&m pan , shift kit and 2400 stall.

um, just a guess. maybe 12.5 or 13. depending on if you had any traction off the line. those are street tires

Re: Thought id show you guys my 85 also
You need some e/t streets or nitto 555's or something for when you want to go fast. My poorly tuned stock 350 in my last truck with 3.08 gears would spin the crap out of ONE of them. They were 26x12 Mickey Thompson s/r's like you have. So I imagine with a 502, a nice converter and 4.11's it will demolish them, even though they are wider and you have a limited slip. Those do look good though. You just might need some stickies to get it going anywhere

Re: Thought id show you guys my 85 also
I would agree with the 12.5-13 second guesses. for another thing, with the leaves alone, you will have axle wrap issues which will also plague your times. get some slappers along with the stickies and hope it hooks like hell!
