1982 Crewcab towrig

[big4x4ride]

Im getting ready to fix up this 82 crewcab I have to use as a DD/tow rig, kind adeabting options for what to do motor and tranny wise when its all done.

I voted for the 454/NV4500 combo - plenty of power and the O/D lets you run more gear in the axles.

I would also work fuel injection into the budget if possible.

 

[big4x4ride]

yeah, if i change to another gas motor it will be injected for sure

If you are talking about pulling some heavy grades with some heavy weights a 6.2 even turbo'ed is going to suck. A friend of mine pulls his K5 with a crewcab with a 6.2L Turboed. His trailer is heavy along with his truck but it is a dog on hills. It does ok on flat ground but if there is any incline involoved it doesn't do so hot.

I would go with a 454/4500, 350/465, or get a 6.5L TD in there.

A 6.5 would be lower power than a Banks turboed 6.2.

 

[Hossbaby50]

Hense the TD, turbo diesel.

I meant a turbocharged 6.5, not NA, I do know the difference.

I would consider a Cat 3208 or 3116 if you are a really good fabricator and mechanic and don't mind using an Allison auto or Clark manual tranny. Next I would consider a 5.9 Cummins, then a 3.9 Cummins, and finally a 6.5 TD. I wouldn't go gas myself because it is so expensive to feed them and a diesel will outpull a stock 454 anyway, besides a 6.2 and stock 3.9 4BT.

 

[Hossbaby50]

So your saying a 6.2L turbo diesel would have better power then a 6.5L turbo diesel? Somehow this doesn't strike me as true, but I don't know for sure. I was under the impression that a 6.5L had better power then a 6.2L.

I have heard several people say that a 6.5L with mods can be in the same ballpark as a stock Cummins 5.9. If that is true then I would bet that a 6.5L has more power then the 6.2L. The 6.2L turbo diesel I have witnessed is no where near the ballpark of a stock Cummins.

I don't know that much about diesels so I can't really talk much about the subject. If I am wrong I am wrong.

I have driven both and own one and the 6.2 with a turbo is far better than a 6.5 if the 6.5 is stock. The 6.5 can make more power of course, but I assumed we were talking a 6.2 with a turbo compared to a relatively stock 6.5, in this case the 6.2 makes more peak power, the 6.5 makes very little boost stock.

Also, early Cummins 5.9s only make 140 hp and 400 ft lbs, that HP number is easily surpassed by the turboed 6.2s, and it is close on torque. The Cummins lugs MUCH better though and is better with fuel mileage.

just buy mine !!! 87 crew cab sngle whl 4x4 Banks 6.2,nv4500,33 12.5 BFG's

I was talking talking about doing similar mods to both motors. If you turbo the 6.2L then do a similar amount of work to the 6.5. Just miscommunication.

You have pictures of it, I would love to see it? Thanks

not uphill...... maybe if your talking about stuffing a very expensive newer and modded to the max 5.9. The cat would be a good option but the allisons are serious bank.

On flat ground from a stop the diesel will obviously outpull a stock 454 but uphill is a different story. With very minor mods he could have the 454 pumping out 400+ hp and somewhere in the range of 450-500 ftlbs.

the 7.3 L will suck more gas and not have as much off idle torque but it will be able to cruise up hills alot easier and still will handle whatever you have to throw at it with no problem considering he has the option of looking into getting one built up... if he can afford a 5.9 cummins or the cat with the allison he can easily mod a big block to pull just as hard as the diesel and harder than it up hills.

 

[mr_beer]

My cummins will use just as much fuel towing as a big block would towing. Around here diesel fuel cost more than gas

 

[dirtwarrior17]

what size is it? I only said that because of the bigger cid.

 

[Cmoe]

Since your talking about a DD too. 6.2

I didn't know ignorance could be so funny....

IIRC I think I read in 4wheel adventures once that the rare dealer installed banks sidewinder 6.2's had slightly more power than the first 6.5's...IIRC of course.
