Non-whistling whistler...why?

[Fat Jack]

OK gimpyrobb, now you got my attention. How difficult is it to "bump up the fuel"?

 

[dm22630]

No, the 427 is NOT in the 5 tons

Its an early version of the ldt

I stand corrected.

Where to begin.... The 427 was the predicessor to the 465. Exactly what it was in i can't remember but it might well have been the a1's. To fat jack: yes that is correct the turbo was put on there to clean up emissions. BUT as a side effect we get to turn up a the fuel a little and get a bit more power. Not a lot but any is nice when you are moving something like a deuce


Looks like i was too slow on the response....

Thanks for the help guys, who knows if I would have caught the difference... anyone know if the gasket between the turbo and manifold is something you can get at NAPA or Carquest? So far i've only seen kits with those in them.
Also will be looking for info on buying or fabricating the cab reinforcement plate for a ring mount... any ideas? Seen some info on that here, but it's fairly old.

Fatjack, it is fairly easy, a search for "turn up fuel" should net you the answer. I have not done it, so I don'r know.

BE WARNED, install a pyro gauge first, as you can melt parts easy with a turned up motor. A pre turbo temp of 1200 is where you want to stop at.

I have a 1972 AM General M35A2 that has a LDT 465D and the data plate is dated Oct of 1987. the engine has 18000 miles on it. It is a quiet turbo and sounds like a cat engine!! Hope my info helps.

 

[Fat Jack]

Great! Thanks for the info gimpyrobb. Don't plan on hauling any heavy loads, so probably won't need the extra power and will just keep my paws off of it.

Chemjohn, I've had good luck with WHite owl and saturn surplus. Don't know if they have them or not.

I have an LDT 465 D dated Oct 1987 in a 1972 AM General M35A2 that is a quiet turbo. The engine sounds like a cat. It has 17000 on it and runs well. Hope the date on engine helps. The truck came from Alaska and had Unit markings from the 172d Bde. It came down from there in 2004 to Montana.
