Peg leg rear with unknown gear

275/60 radials all the way around.

Nothing removed from truck. I 'll give you guys a couple days of guessing before I post a times.



This was a 6cyl 3 speed truck what gear should it have?

Re: What do you think this ran
 

im guessing with the sixer the gear was Alittle Lower then usual?.....

Im guessing a 12.9xx

Re: What do you think this ran
 

I think the rear gear is key to guessing how this stock set-up would perform, but I'll guess 15, based on a highway gear.

Re: What do you think this ran
 

Im gonna say 9.8 @ 70 mph in the 1/8. Chris.

Re: What do you think this ran
 

Still the manual 3speed?

If auto, how big of a stall?

Re: What do you think this ran
 

turbo 350 2000 stall

Re: What do you think this ran
 

60' --- 2.12
1/8 --- 8.82 @ 81.4
1/4 --- 13.76 @ 98.7

Re: What do you think this ran
 

pretty tough with the limited info there Kevin,, but I'll bite

14.2's at around 85-90ish mph,,, guessing it had 3.73 gears from the era which seems was common with manuals and straight 6's,, but if it was one of the hwy gear trucks (3.0x gears,,, closer to 14.9's or more would be my guess.

Re: What do you think this ran
 

Well I'm guessing it must have run pretty good if you are posting. My truck had a similar setup but with 3.42 instead of the original 2.73 and it ran mid-14s. So I would guess 13.9 @ 98.
My truck was an oringinal 6 cyl, 4 speed and it had the 2.73 rear gears.

Re: What do you think this ran
 

am i the only one with faith in the peg legger(ok i was generous but whatever)
is the action plus a dual plane intake? and is the xe262 a flat tappet or roller?


I want to see pictures of said truck:lol:

Re: What do you think this ran
 

dualplane and hyd cam

Re: What do you think this ran
 

Mid 15's 1/4... High 9's 1/8...

Re: What do you think this ran
 

14.7

Re: What do you think this ran
 

With a correct peg leg dual burn out and air pressure adjustments . 13.95 @ a tad under 100 .

Re: What do you think this ran
 

I'll say around 9.00-9.10 @ 80 and 14.00 @ around 92 or so.
As far as the gear is concerned, I was under the assumption that most of the 6-cyl/ 3spd manual trucks came with 3.73s.

Re: What do you think this ran

I think some of you are forgetting these pigs weigh about 4000 pounds.

Re: What do you think this ran
 

I guess 15 flat in the 1/4

Re: What do you think this ran
 

We think the truck has a 3.42 gear but not sure. It turns about 2700 at 70 mph with the 28 inch tire.

Best 1/4 ET @ mph: 14.74@91.55
Best 1/8 ET @ mph: 9.46@75.02
Best 60 ft: 2.202 on Radials
Engine: 350
Transmission: TH-350


we are planning on doing a 383 with fast burn heads and a posi of course.

Re: What do you think this ran
 

i gonna say 13.80 @ 80 ish.

Re: What do you think this ran
 

Sounds more like the famous 3.08. That's about what my truck does with the same gears and tires.

Re: What do you think this ran
 

15.55-15.65 at 72-74 mph

Re: What do you think this ran
 

I posted the times in my last post.

Re: What do you think this ran
 

:) WAY TO Go Dude!!!!! Nothng like NAILING it from the hip! :)

Re: What do you think this ran
 

I am the owner of said truck. When I got home this afternoon, I checked
the ratio 43 tooth ring gear and 14 tooth pinion gear so it is a 3.08. What do you guys think it will do with a posi and 3.73 rear gear?
