Planning on buying an old 70s I think, Dodge 600 with a v8 Gasser. Was told it ran when parked. Comes with a 4 speed manual, PTO and very clean inside, pretty clean outside. Problem is, been a long time since I seen one of these. Anyone know anything about the Dodge 600?

I'm looking to find out factory motor size,
Are they good trucks?
Anyone know the size of the rear diff?

If I bought it, it comes without the dump body and would be buying it from family so the price is really nice. Just wondering if anyone knows anything about these and where to get parts, and are the parts expensive?

Just going from memory, I think Dodge built the last of these in 1974. The engines were the same as the 100-300 series, 318,360,400,440.
parts for the 440 are scarce and the 400 was discontinued in 1978.(I had 1 of the last ones in 78 W150) However 318, 360 parts are easy to find.
The transmision is likely a Spicer and not sure of the rear end, But I do have the 1976 truck service manual and the 600 is still in it, so I will look it up and post it here when I get a chance.

Thank you, I appreciate it. The only thing I found out so far was that supposedly it has a "mechanical motor" which I was told revs at a higher rpm and therefore a replacement motor for this would have to be the same as what comes out of it. Not sure how accurate that is. They told me the crank is snapped in it, so without me having a shop and the tools, fixing it is impossible. Would have to be a motor swap I think.

Other than that I got no more info on it, other than the interior, shell and trans all look good. Btw it does have a spicer in it I found out.

Hi, I looked up in my manual and if it is the 4 speed it will be either the new process 435 or 445. if it's a 5 speed then it's the new process 540-542 or the 7550-7590 transmision. there are several rear ends possable depending on if it's fixed or 2 speed rear end. for the D600 there are 4 listed F147, H141 single speed and 15201,16221 2 speed. For the D600 the engines listed are the 318-3,360-3 and 361-4. If it has the 361-4 you will have a hard time with a direct replacement as that engine is a short stroke 413, rare these days. however any 70's early 80's 318 or 360 should work fine. Hope that helps, good luck with the project.
Also be on the look out cause there was a 4X4 version of the D600.

Thank you and yea i seen a 4 speed in it when I opened the doors. With this info I'm going to look around for a motor, if I can find one, I'll buy it and rebuild this. I really appreciate all the info and help.

I love those trucks. I see D600's for sale once in awhile on CL or elsewhere and man it's tempting but I really just don't have enough property. I wish I could have one. What great looking beasts!

A short stroke 413 is usually called a 383 LOL. Except the 361 is a smaller bore 383.
Without the specs though, I can't say if a 383 crank would drop in - some 361 engines used weird cranks.

If it is a standard big block bell housing, almost any 383 crank should work, but honestly unless you want just to say it's a 361, why not go 383/400 or even 440?

Most of the dash engines 361-3, 318-3, etc were a bit heavy duty but mostly in the cooling of the heads, etc. Some of the blocks might have been a bit better like the very early 400 block - the strongest of all of the BB blocks , except for the hemi.

"If it has the 361-4 you will have a hard time with a direct replacement as that engine is a short stroke 413"

If it is truly a RB block vs. the B block (although, I thought that the only smaller displacement big block that ever had the RB block was a few 383 RB engines made - however in heavy duty truck anything is possible), depending on the bearing size, it could use a few different crank options - as long as it isn't a long crank engine.

If the main bearing journal is 383 size then a 383 crank could be used, I think all 383 cranks prior to 70 were forged. Cast 383 cranks were fairly rare, but cast 400 cranks are common - forged 400 cranks are rarer.

If the main bearing journal is 440 size then a 440 crank could be used, before 70 should be forged crank.
