convert from diesel to gas??

[DesertDueler]

Has anyone converted a truck from a diesel to a gas motor. The reason I ask is I have no clue how to work on a diesel and 1 found a 84 1 ton GMC crew cab. I would like to put a 454 in it and wondering how hard it would be and whats involved?

I know this isnt a common question.

DD, I watched a buddy convert a diesel crew cab K30 to gas once. He simply bought brand new fuel tanks, thats it.

Once the diesel was pulled out, and the old fuel tanks, he took some brake cleaner and squirted it into the fuel lines running the length of the frame rails. He capped one end off and shot some compressed air into it. Not much, just enough to run the brake cleaner to the other end. Then he went to the other end and repeated the step as he first started.

After he did that for about 4 times, he finally just blew the brake cleaner out of the lines and got the tubes 'clean'. He went to the other end of the line and blew it out too.

Finally, the new tanks went in along with the small block he built for it and got it all running just fine. You would have never known the difference.

The whole idea here from the swap is to make sure all the old lines are clean and rid of the old fuel.

I have heard of some people cleaning and draining the old diesel out of the same tank and reusing them, but that method is not recommended. Brand new tanks are the more preferrable method.

Is there any woring I ave to worry about? I would put MSD ignition on it so I wouldnt have to worry about the electronic ignition wires, but any other wires?

The only thing I would be concerned with is that the diesel won't have all the wiring/etc. to put the smog controls on and pacify the Maricopa Co. smog-Nazis.

Yea I forgot about that. I guess I would have to figure that one out to.

I would put the MSD on anyway. I love the thing. It was the best thing I've done beside the swap for the 350. I have the MSD 6 Offroad box. It costs more, but it is water proof and vibration proof. It helped out the MPG and the throttle response alot. I wouldn't trade it for anything. Go to Checker and tell them to order it. They will match Jeg's &amp; Summits prices. The Offroad box is $215 or so.

Thanks, but I already know that. Ive got it on my Firebird. Its required when you use nitrous.

Which box do you run on your Firebird?

 

[DesertDueler]

I run the MSD 6Al box. The one with the rev limiter.

This talk is just plain craziness!! Keep the Diesel, you'll be sooo glad you did. First, think of this: you didn't know how to work on gas engines when you 1st got one, did you? Next, there's a reason more Diesels are used in industrial app's than gassers; it's called simplicity (longevity, torque, and fuel stingyness are all just side effects...nice side effects). Now, keep the Diesel (or sell it to me...no, give it to me)

If you have a auto tranny in the truck you will have to change the torque converter. I am not sure if there is anything needed if it's a manual tranny.

See Ya,

Double_T: (Daffy Duck voice) NO IT'S MINE!! DOWN!! DOWN!! MINE!!

Simple, KEEP THE DIESEL. And if you really don't want it sell the whole thing and get yerself a gas guzzeler!! Think...you get how many MPG with the gasser...and how much with the Diesel?
Gas=1 mpg Diesel=20+ mpg ON A FULL SIZE BLAZER

Now...hand over the Diesel. &gt;
