What Engine Did I Get??

[NVW]

I would have to search for it but IIRC it is the last 3-4 months of 95.

In general the 599 came from 92-94(some early 95's had them), 929 was 95, 141 was 96, and the 506 was for trucks built 01/97+. The 141 has been found in 95's, but oddly enough some 96's have been seen with 929 blocks. The 929 is sort of an odd duck as it was pretty much only used for a short while in 95 and from what I have found had the shortest casting run of any block I've ever seen. I asked PEN about it before and even they were puzzled when I told them I had a 929 block in my BURB.

141 is a squirt block?

 

[NVW]

No, the only squirt blocks were 506

 

[davo727]

I have a 141 block, its cracked

I also have a 1992 599 block- its cracked too

Should be on the sticker in the door jamb, on the top right there is a month and year date.

I thought we didn't like oil squirt blocks?............Or is it the other way around?

Well?

 

[NVW]

Well?

The oil squirt is a good thing but the blocks a more prone to crack. So generally people look for a non oil squirt, usually the 599 block.

But, the AMG Optimizer and P400 are 506 blocks....Correct?

The OPTIMISER is, but I don't know about the P400. That is where the date stamp comes into play though, and the INTERNATIONAL diamond cast into the intake valley.

So we don't know if a P400 is a squirter?

NVW, what build date was your 95?

In general 929s came about around the 95 model year, and around the 96 model year the 141 came out.

09 of 95

 

[buddy]

09 of 95

So yours likely got made at the same time as the 96 model years that came out the next month.

Yes, but they are also built in a differnt decade with better metalurgy and machining

hey guys my dads truck was made 01/96 what motor do probably have???

the motor has the single t-stat and the 95 air intake on it if that helps...

You likely have the 141 block

 

[6.5dragracer]

well is that the bad block or is that the ok one...

does mine have the oil squirters???

 

[Matt Bachand]

I think all factory blocks are fine as long as they have not been overheated and properly maintained. I've put 50,000 miles on my 97 squirter supposedly the worst block.

As I redundantly say, the factory gauge shows RED temp at 260.

Common folk pushing these trucks were pushing the engine tough at 230+ thinking it was safe... This is a 6.5 death sentence.

My .02.

 

[buddy]

They are all fine, unless you happen to actually get one of the 97s that was actually drilled wrong and basically came precracked from the squirters. So yes there were shitty 506s in 97, but lets say maybe only 80% of them used from Jan-Jun 97.

And some of the block castings are actually known to be stronger due to metal content. So although all of them that came properly cast are fine for stock power levels and adhereing strictly to towing limits, there really are differences in them.

But as Matt says, people didnt know that when the gauge read 230 cylinder 8 was blowing its lid from coolant imbalance and the extra turbo heat. And people associated diesel with grunt so try towing heavy stuff or stuff that is a big sail and blow them up.

Wow thanks for all the info guys. So should I install a secondary temp guage for the engine since the stock one is so inacurate? I might as well try and save the 506 i have in my truck right now. And the hotrod is not doing that great. Its in Red Deer getting the tranny rebuilt. I told them i want it to handle what ever the hell im gonna throw at it. And not to go for a long time! So they put in a shift kit alto clutches and a heavy duty torque. Hopfully im good for a while.
