What do you think fellas? https://www.facebook.com/share/1WY1dQ46y9/

That's probably due to fretting which is common on the whole 855 family, specially upwards of 500hp..after so many overhauls , probably an out of frame , resurfacing the block and main caps and then a line bore to bring it back to true woulda been needed .

I second that.i would love to get my hands on a pln 427 with a 13 speed and 3.86 gears to pull my end dump...spice it up with a blixton module, oversized injectors and upgraded turbo.. -

Yes, agreed , i meant for the listing to show what engine brake valve cover spacer looked like.. would like to also add that maxidynes are usually paired with 5,6,7,8 speed maxitorques trans which have an end overdrive of .64 -

I'm not sure what chassis he's working with. But unless he has a CL or rw ,he Will probably have to shoehorn it in there..lol..... And if so, b model cats seem to be making a comeback. There's a couple guys out there that are building 600 hp b model kitties 😻. -

https://www.facebook.com/share/14SusdGPbNi/ Something like this is what you're looking for. Price is a bit high, but it has engine brake. Like previously mentioned, you can tell it has engine brake spacer between the valve cover and the head. -

Test for static pressure and under load. If you get hose long enough,you can zip tie it to the windshield wiper and drive it around the block.Dont remember the most minimum pressure requirements but someone here will chime in.

Hello all, joining the conversation late , yet I would love to chime in. Brett3876 I believe was using a mechanical e7 with 454hp pistons for decreased compression.Turned up pump up with matching injectors and turbo.He has some YouTube videos up I believe.I was very impressed by their set up. -
Your right... usually one can tell they're plugged because seals get moist and don't yet leak , also the bolts holding the traverse torque arm bracket. On this case it was the overfilled banjo housing, bearing back lash was not in spec but not loose enough for both seals to fail at simultaneously.

Yeah that's the first thing I did. Vent was clear

Eaton most likely, while personally I like mack transmissions for their robustness and a bit extra overdrive.eatons are far more available in this area and cheaper to rebuild.and The truck is not mine. Is my buddies. So he has the last say.

For now we'll make the 10 speed work , but will definitely be hunting for a 13 speed core to rebuild.as of now it seems to be a very reliable truck, only thing is has asked for was a set of wheel seals , previous owner replaced both diffs with reman units and the front diff was about 2.5 gallons overfilled causing in my opinion excess pressure and blowing out seals.
