3406B/C Frankenstein

I was taught exactly like @Diesel Dave real one in like your gonna drive it so to speak. I would give it another couple turns and let it eat.

New nozzles will cause a power complaint till about 40 to 50k on the miles. They seem to spray a bit better or maybe hone the holes after a few miles. So I’m sure it’s got a bit more either way. It’s always nice to hear one come together as hoped

 

Does anybody haul equipment with a B model?

 

We do.

 

I see it coming they need big power to pull permit loads…..

 

Funny thing about that is, unless you crank any engine up beyond where it ought to be, you are going to go slow up the hills regardless. If you are trying to pull 130k up 5 miles of 6% grade @ 60 mph, something is going to come apart fairly soon. That said, some of the best races I have ever had have been below 35 mph, where one truck has maybe a half mile per hour on you, but the hill steepens just a touch, he has to downshift and you don't, then you have a half mile per hour on him! A guy WILL push the limits in that situation, which is why it is smart not to have it turned up too much.

The answer for @pipedaddy is, in my opinion, you are not going to quite keep up with the 550s and 600s, or at least not for long, but you can stay dang close to them. The difference is that newer engines have a computer that helps protect the engine from ####### stunts and leaving your foot buried in it (if it doesn't have a wild-### tune), while the B model will let you keep going until something breaks if you don't learn when you need to back out of it and let her breathe a little easier, especially if it is turned up at all.

We don't get real heavy compared to the big boys, but we will gross up around 140K pulling in the mountains between 4,000 ft. and 9,000 ft. We just don't get in a big hurry. I bring up the elevation because even though ambient temperatures are generally cooler, the lack of oxygen makes a substantial difference on cooling. On the interstate with mild grades we can keep up with the speed limit and run with traffic until it gets a bit steeper.

 

Mods can we pin this response. No truer words ever been said here

 

I have a 7w3906 pump and 4 bolt advance, would start screw be set to the same 1.1 on it? @wore out

 

Are the 4 bolts 6 point with a 9/16 head? If so yes


If the 4 bolts are 12 point with a 3/8 wrench size no.
This one you only want 4 threads sticking out of the nut. It’s also really flat face looking or cab verses the other style being more of a cone

 

Mine is a 4 bolt 12pt 3/8 head, long story short alot of mistakes have been made on this 3zj and I'd love to pick your brain on it lol, is there a measurement my start screw is supposed to be factory?

 

@wore out I'm sorry I may have misread your reply, on my flat one with the 3/8 12pt are you saying the start screw is only supposed to have 4 threads out?
