I was given an 82 cutlass with a diesel in it. The person who had it was going to junk it. I ask if i could have it cause you don't junk classics cars. so here my problem I want to put a gas motor in it. what do i have to change? My thinking is the heads, intake, put a dist in plus new fuel tank and clean the line. I have read some of what is here on the diesel motor and it sound like i can punch and stroke the block out to a 411 i think that what it said. Any help would be great thanks. Charlie
PS restoring out gm product is my hobby

 

your thinking is correct. you will not have to replace the tank. just drain it out. you will have to change the fuel pump i think.

 

what about the wiring harness. what need to be changed or would i be better justed getting a new harness for a gas motor if it will plug in to the wiring box.

 

Lots of racers like to build that DX block for 1/4 mile use. Very strong, with good bore/stroke potential. Why not build yourself a street/strip motor out of what you have?

 

Just pull the diesel and sell it for the block. Get a 350 or 403 Olds gas engine and drop it in. Change the vac modulator on the trans. If you have cruise control , you have to change the controler. The fuel tank is good to go. All you need is a keyed hot wire for the HEI.
It is NOT worth the effort to convert the diesel to gas, just put a gas engine in.

Awww I love the diesels...too bad you want to replace it. Seriously, if you have it running good, it will last forever. Granted the power isn't the best, but they are becoming more and more rare....and they get really good mileage for a tank!

 

You're right. Just send me your address and I'll come pick up that "worthless" DX block for free...

Gene is right however. If you simply want to convert to a gasoline engine, it's possible to convert the diesel short block but it's more cost effective to simply replace it with a running 350 Olds motor. Once the diesel is out THEN start building a killer motor as time and funding permits.

 

The head bolts holes on a gas cylinder head will have to be drilled to accept the larger diesel head bolts.

If someone need an old 350 D or DX, we have so many in France..

 

Why you want to do so....

What wrong with your car???
