8v71 N serial # 08VF001622

Can anyone tell me the hp rating and the injectors this came with?

Also, does that # tell whether I have a block that can be equipped with an aftercooler?

And last but not least does DD tell what CR the pistons are?

I honestly did try Interstate diesel before I hit all of you up.

Just trying to keep folks busy is all Cheesy

Thanks,
Rick

Rick;

The 8VF stands for a 92 series engine if it were a 8VA it would be a 71 series. now that I have the correct serial number ( brain fart on my part ) I will see what I can find for you. OH and stay away from interstate some of the worst parts in the industry.

Hey Don... while your checking, could you see what you can find out on my Detroit??? I was told it was a surplus military tank engine.
I've got a few more numbers than Rick has but not sure if the extra numbers mean much. My block is stamped with these numbers:

                                                                                                                                                               8VA-445914
                                                                                                                                                                7083-7395

I have to say I'm stunned... all the mechanics that have worked on this, run the rack, checked injectors, checked the blower seals etc. Not one person mentioned that I had a 92 series. I used to wonder why they would paint an 8v71 Silver.

The idea that I have had wet sleeve motor all this time and how I was so weird about getting this motor hot that I rebuilt the whole cooling system. Which had the 8V71 cooling system radiators and pulley I might add, nothing ever hinted that I had anything other than an 8v71.

Getting a few more horsies out of this girl just got alot easier. Finding a turbo and all the plumbing just got alot easier as well.

I have decided to learn how to run my rack myself, I've got a friend who is a good mechanic who has offered to teach me.

BTW wifey and I are considering either Arcadia or Quartzite this winter.

Man I got myself an 8V92... That means that for a couple months last year I had two of them. I sure wish I would have known that I would have kept the other one for parts. Oh well live and learn I guess.

Andy, left side below the head a flat spot at the front of the block if not will be in the middle  below the air covers.Rick check the block on the left in front of the head on the deck should have 92 in embossed letters also check the cam balance pully on the right should say 8v92 there.
If that is your correct serial number I hate to be a bearer of sad news but that is a old oil drinking GREEN block 92 series a very early one at that


good luck

I just went through all my receipts and not a mention of motor type on any of them. If it is a 92 series it must have been right when they made the switch because the aux drive pulley clearly says 8V71. I am wondering if I started celebrating a bit early.

I did check the serial # and it was correct.

We shall see

 Huh Angry

No embossed letters that I could find Clifford. I guess my dream of having an 8v92 and a relatively easy power upgrade is probably gone.

And Nick is till making fun of me.

It's a cold cruel world
