I've been doing some measurements of my own and the R600 front axle is about 5" wider overall than the B model front axle.

According to my wife: "Everything you own is worth what it will bring across the scales".

That is a direct quote. I only wish I weren't serious.

And that is only $2.00 a hundred right now.

Now that I'm single - - - (20+ years)

I don't think I would ever name a truck "Lard A$$" - - - Just wouldn't be fair to the truck!!!!!

We know why your single now...

Well at least now I know I'm not the only one with a understanding wife.

If it turns over then it will probably run. I always get nervous about the valve springs when they sit up that long. I've seen more than a few engines drop a valve due to the springs breaking from sitting up so long in the same place.

Good luck with it.

Looks pretty straight, have you barred it over yet?

As a "big city boy", we don't have this sort of activity. Although street racing is very popular here, i have to ask a question. How is it that three trucks broke traction and headed for the side lines? Too much torque, bad dirt surface? What gives?

As an EX big city street racer from the 80's, Im not judging you but street racing is bad news these days, the cops don't have a sense of humor about it anymore. Here in Texas it can turn into a Felony real quick if something goes wrong.

As to your question the track "dirt surface" is normally a clay mixture that is kept slightly moist to help the tires bite without digging in too much. There are several things that can cause the trucks to veer left like observed in the video. Here are just a few; uneven moisture on the surface, previous puller dug out ruts and left soft spots in the surface, uneven track, track wasn't packed well to begin with so the later pullers don't have a good firm consistant pulling surface, etc. etc.

You should get out of the city long enough to go watch a tractor pull sometime, you will be amazed at the technology and power you will see.

I got the old truck home a couple of hours ago. I should have some cheap R600 parts for sale very soon. Going to post in the for sale section as well.

Great vid. We started pulling in the street semi class about 2 years ago.

Check out some of the vids on you tube under my board name.

I already had your "last call" youtube video saved to my favorites, the old dog sounds pretty good.

I have a few vids of some of my junk posted on youtube as well.

Nice looking truck. The track sure went away for the later pullers, looked like the moisture started coming back to the top.

This is my favorite Mack puller, at least for now.

Keep us updated.

Thanks Dak, I plan to use 11-22.5 rubber on the old dog. Here is a website I occasionally use that has some helpful automotive calculators. http://www.wallaceracing.com/calcmph.php

Another quick and easy to remember formula is mph x 340 x gear ratio / tire diameter = rpm

I have just about got the wife (warden) convinced to let me drag that R600 home long enough to get it parted out.

How much is a good used TR1076 with a PTO worth?

LB, good luck with your project. I found this photo of a pickup truck that Mack actually did build for a short while in the mid 30's.

Thanks, I'll bet those old factory built Mack pickups are worth a fortune.

I first saw the 2050 in the mid 80's. I have 2 in stock at $500 each. Keep in mind these are very fast transmissions. .6 to 1 overdrive. That means if your truck now runs 60 mph at 2000 rpm, with a 2050 it will run 100 mph at 2000 rpm.

David, if I end up buying this thing, that .60 OD will be perfect with my 5.83 gears. $500.00 doesn't sound like a bad price either.

Ok, went and looked the truck. The engine sounds good, good oil pressure, etc. No intercooler or aftercooler the boost goes straight from the turbo to the intake manifold. The transmission has 1076 stamped on the side and Maxitorque emblems cast in, it also has a good PTO on it. I am assuming this is a TR1076 5 speed, which is direct 1 to 1 in 5th correct?

BTW Paul, the rear cab corners look solid.

The VIN starts out R685T

If I end buying the R600 I should have plenty of leftover parts that I have no use for and I will certainly keep the cab corners in mind for you.

Can someone tell me when they started using the T2050 transmissions?

Thanks Greg, those do have a shape that might look good on a B pickup. I'll have to improve my photoshop skills to test the theory.

What would it take to install a T2050 behind the ENDT675?

I am thinking of buying a 1980 R600 that had a cab wiring fire for parts. It has a ENDT675 (235HP) coupled to a Mack 5 speed. The old engine runs good and I'm thinking about shoehorning it into my old B20. I can get the whole truck fairly cheap, use what I need and part out the rest to recoup some of my investment.

Is the Mack 5 speed used behind the ENDT675 in these trucks an overdrive transmission, or is it direct in 5th?

That is pretty impressive. How much boost? Are you running nitrous?

Looks like an awful straight truck to chop down! Terry

Not going to chop up the Mack, just fabricating a bed for it and it will be removable if needed. The B20 will keep the original cab, chassis, and running gear, although it will probably end up with more HP than it originally had. I was just trying to get an idea of how it will look when finished.

I am going to build a B20 pickup and wanted to get some opinions on the bed lines I am thinking about. I will be fabbing the bed up from scratch so I am only limited by my wallet and time. I found a Google picture of a B20 fire truck then did my rookie version of photoshop to get an idea of how the finished version would look. My truck will go back dark green, not red, but I'm thinking the bed lines will be very similar to the picture. What do you guys think?

Is Joe Walsh running again this year?

It doesn't look bad but I think the seller sure could have done a little more with additional pictures and a better description.

I see said the blind man, a picture is truly worth a thousand words. I appreciate everyones help.

I'm getting ready to order a complete glass kit for my 1953 standard cab B20 from this place.

Is the standard cab designated a CA30 model?

I was looking at B67 pictures trying to see the difference in my B20's cab and could not tell much from the photos, most photos of them are from the front. I'm 6ft. / 240 lbs. and the B20 cab is kinda cozy. Is the difference in the curvature of the sides where it makes the transition to the back of the cab?
