71 swb fleetside
Gm Goodwrench 350
Weiand Action plus
Speed demon 650 vacuum secondary
Comp cam xe262 .462/.469 262/270
hei distributor
5/8 hedders
2.25 exhaust
40 series flowmasters


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

PhilaTruck 02-09-2009 03:11 PM

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.

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

Still the manual 3speed?

If auto, how big of a stall?

Super73 02-09-2009 04:59 PM

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.

Wild83C10 02-09-2009 06:04 PM

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.

joeys66pickup 02-09-2009 06:25 PM

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:

djracer 02-09-2009 08:12 PM

Re: What do you think this ran
 
dualplane and hyd cam

383 Stroker 02-09-2009 08:52 PM

Re: What do you think this ran
 
Mid 15's 1/4... High 9's 1/8...

Pyrotechnic 02-09-2009 10:33 PM

14.7

hotrod 80 02-10-2009 12:04 AM

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 .

nxtruck 02-10-2009 12:12 AM

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.

LuckyHenriksen 02-10-2009 02:29 PM

Re: What do you think this ran
 
I guess 15 flat in the 1/4

djracer 02-10-2009 02:54 PM

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.

meansting04 02-10-2009 03:05 PM

Re: What do you think this ran
 
i gonna say 13.80 @ 80 ish.

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

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?

Nice truck! Welcome to the board.

djracer 02-10-2009 09:23 PM

Re: What do you think this ran
 
welcome to the board Jason. I have located my old 377 short blockout of my old white truck! We might be able to get it cheap!

hotrod 80 02-10-2009 09:36 PM

Re: What do you think this ran
 
welcome to the board . I guess i was gambling it had a 3.73 . Nice truck .

Nice looking truck!

Wild83C10 02-10-2009 10:27 PM

Re: What do you think this ran
 
The 3.08s are probably helping you launch better since you have the peg leg. I would guess that the 3.73 would make traction hard to come by. Although if you get a good launch then you could cut a couple tenths off I imagine.

jgreene0717 02-10-2009 10:33 PM

Re: What do you think this ran
 
I will be picking up a complete rear
end out of a 68 truck with a posi
unit and 3.73 gear. I am just going to swap axles if possible. Some say it is others
say no go. But we will soon see. I will post new times when I get it all swapped. Thanks for all comments it is a work in progress.

Re: What do you think this ran
 
Good looking truck Jason. But it was faster than that when it had the 305!

djracer 02-11-2009 08:29 AM

Re: What do you think this ran
 
come on now Sam I'd rather have a sister in a whore house that a brother with a 305!


Welcome to the board!

sams442 02-11-2009 07:18 PM

Re: What do you think this ran
 
Jason said the 305 has made him a great boat anchor. Heck I did'nt even know he had a boat!!! Thanks for the welcome Kevin. Jason just messing with you. You really have that truck getting up pretty good. I went by the old house today to see if the rear end was still there, it was! Give me a shout when you are ready. Later Sam

jgreene0717 02-11-2009 09:16 PM

Re: What do you think this ran
 
I will talk to ya about picking up the
rearend tommorow. The 305 is actually in a 55 chevy bel-air right now being used as a mock up motor.
Thats the only thing it is good for now after it came apart on me at about 5500 rpm.

sams442 02-11-2009 10:10 PM

Re: What do you think this ran
 
It would be nice to know what it would have run at the track with the "mock-up motor" Ha Ha. Just to compare !!
