weight

[buildin72]

I know this question has been posted before, but i cant find the thread for some reason. Does anyone know about what a short bed 2wd truck would weigh with small block in it?
Thanks,
A.Y.

My 68 cst longbox big block weighs 3950. Sorry dont know on a swb.

[buildin72]

alright. thanks. appreciate it!

[buildin72]

What would a small block weigh alone, compared to a big blocks weight? I'm thinking about postponing my 72' 4x4 cummins conversion project for a 70 shortbed 2wd truck my grandpa gave me, and running a Cummins 4bt in it for an engine. I'm just trying to figure out about what it would weigh compared to a basic truck.

Thanks

I'm thinking a small block is about 500 and a big block is about 700. Some one please correct me if I am off.
My ols SWB with a small block came in at 3900 pounds. It had alluminum wheels, intake, lighter headers, no spare tire... no clue why it was so porky, it even had the TH350 instead of the brickish Th400. If you want to go by GM's numbers, dry shipping weight is supposed to be 3562.

So does the 4bt have the same flywheel housing as the 6bt ? I'm a big Cummins fan , easy to hotrod . I'm getting ready to do some mods on my 05 Ram . In my area diesel 4x4 trucks rule , easily out performing the gassers . I may have a 4bt operators guide and parts / service manual around here somewhere , i'll check . Good luck with the diesel.

Let me climb up on my soap box here...



<rant mode on>
Performance wise, the only reason a diesel runs harder is the turbo. I can't think of a single non turbo diesel that is any fun at all.
Put a turbo on asmall block and see how fast you go.
No,wait, the modern diesels are all mege cube.... so we'll have to put a turbo on a big block chevy to make it a fair comparison.

I'll give you durability and MPG.... but everyone brags about the power, it's apples to oranges, and a moot point if you are dealing with aturbo on one and not the other.
<rant mode off>
I have my flame retardent suit on, so go ahead and flame away, BUT, no one can argue what I just said. Get a big block and put a turbo on it and prove me wrong.

[Longhorn Man]

oh yeah, the 4bt is the same as a 6 bt except a couple cylinders missing. Bellhousing is the same, and you can get adapters to hook up a GM tranny.

[buildin72]

Thanks Longhorn Man. I knew you would chime in on this. I appreciate it.

409biscayne...I'm not sure about the bellhousing part. I'm know more about the 6bt myself...and dont know a whole lot about THEM. I posted some 4bt questions on a local diesel site, they will probably help me out. You should join the site. www.kydtr.com If your a diesel fan youll love this place. Its a good informative diesel site. Im futuredieseltech on there. Come on over and join.

DAM*! I cant argue, Longhorn Man!

Just gotta add my $.02!!
I just want my truck diesel powered, just to be different. Im a diesel nut...if it has a diesel engine...im interested. I just think it would be neat to have a 67-72 chevy 2wd, swb, street truck with a 4cyl cummins in it, straight piped, and puffing smoke. With a few mods i believe this truck would be bad news. Granted its not going to run like a built small block, but it will run well to say the least, with enough torque to pull a house down!!!

Ill admit what you said about the gas engines and a turbo....BUT you have to admit with modern technology...some of the new diesels are bad a**!!!
Look at the new Duramax LBZ. 360hp and 650lb/ft torque! Ive talked to people who have drove this truck and they say with it mated to the Allison tranny, that its a rocket. You gotta admit... with some of these trucks weighing in at over 7,000lbs they will flat SCAT!!!

There you go. I wasnt disagreeing with you...just re-agreeing!

A.Y.

[Longhorn Man]

I do admit they'll move, and like I said, they'll out last and out MPG a gasser. I guess I'm just used to some of the locals around here talking so much smack about the output of a diesel.
Now, on the 4b, I am not to impressed with it honestly. We were doing 4b conversions on P/30 step vans at work, and the 6.5 non turbo was out doing the 4b. This is actually the 4BTA I am talking aobut too, not just a generator engine 4b. With the 4.10 gearing, and the aerodynamics of a brick wall, they maxed out at about 55, once in a while we got one up to 60. The 6.5 was always able to do 65 in the p/30...at least, when the engine is new anyways. The low end was rather dismal too IMO on the 4b. I'm sure there are upgrades, and I can't speak for a modded one. But in stock form, the 4bta is not all that impressive. It may be OK in a pick up, but probably won't be anything to write home about.
It would be neat, not arguing with you on that either. Loud (clattering diesel loud, not rumbleing pipes loud), but neat.
Here soo, our shop will be the only one performing the Frito Lay truck rebuilds, and after we do another 30 or so, They won't be having any more rebuilt. Pepsi-co fell victom to new tax laws and it is no longer cheaper to rebuild the trucks. We are going to do enough to use up there supply of engines and trannys, then it'll all be done.
Since we are going to be doing it all in house, I should be able to get contact info on some companys that offer conversion cross members, motor mounts, bellhousing adapters, and in all reality, anything else you would need with the exception of tougher springs. I would think a 4X4 front suspention would be better for the 4b, it is a porky little sucker and taxes the coils pretty good on the few independant front suspention trucks we've done. The leafs we install are pretty stout units too.

DO you think the 4bt will be too heavy for the 2wd 1/2 ton front end?? And how much will a good 4bt cost?? What do you believe the swb will weigh with the 4bt??

[Longhorn Man]

If you installed one ton springs, it might be OK. i don't know the weight, but I can try to find out though. It'll be a couple weeks before our conversion program gets going. We just finished the last one under the old contract of one a week with there assistance for paint, body and int work, now we get to do the whole thing. Any pepsi-co workers that worked in the frito rebuild department is going to be out of work in 2 days. Now we get to negotiate with pepsi-co as to how much we'll get for a full on rebuild, and how many we'll do a month. Once that program gets going again, I'll have contact info on the vendors that supply the parts, and I'm expecting a shipping label of some sorts on the engine, which should include a weight.

[buildin72]

one ton Springs!! well this throws a clinker in the whole thing, beings how i wanted to run a 4/6 drop on my truck! hmmm. ponder, ponder, ponder!!!

[buildin72]

Heres a thinker. How much room do you think you would have from your turbo to the surrounding areas in a 67-72 (frame rail and firewall) with running a 4bt? Is the 4bt set up the same as the 6bt??...as far as the turbo being on the passenger side, with the intake and injector pump being on the driver side?? Someone told me the 6at is the complete opposite as the 6bt in those areas. Anyway what i was thinking...is if there is plenty of room around the turbo, maybe i could run a twin turbo setup??? We'll ge power out of the sucker one way or the other!!

Just a thought.

[Longhorn Man]

well, the turbo is on the passenger side, and the engine is kinda small. I don't think packaging will be an issue. Twin turbo....hmmmmm, sounds expensive.

[LonghornJeff]

listen to Longhorn man.......He made a 500 Caddy fit in a Lincoln (The trunk!)

[buildin72]

Well, got the specs on the 4bt. The weight kinda surprised me...figured it would be a little heavier. Kinda disapointed in the hp. Torque output i could work with.

dry weight:700lbs
HP: 105
torque: 265

[Longhorn Man]

LOL!!!!!
He is right... I did that. I also made a couple 350's fit in there too, but not at the same time though.

Ahhh trust me...Ive figured that out over the past few months!

[Longhorn Man]

I'll try anything twice.

[buildin72]

Figured id post the specs page in case anyone else is thinking about this cluster**** conversion.

BTW... Longhorn Man...pretty funny pics. Can't say ive ever seen anything like that before!

[Longhorn Man]

heh heh heh.
