I have a 1989 D-100 with a 318.Does anyone know if someone makes an adaptor to remove the trottle body and put a carb on it or do I need to change the intake?

 

I'm not aware of anybody making an adaptor plate. There's more too it than just slapping a carb and a new intake on there, too. In addition to the new carb and intake, I'm pretty sure you'll need a new
Distributor
voltage regulator
Electronic ignition module

Plus, I think you'll have to convert your EFI pump to an older unit in order to properly feed your carburetor, and you'll have to alter the engine timing too, I believe.

And if you have an automatic I'm not sure it'll still shift correctly without the computer actively running your motor. I've never done it, but I've read about it a bit. Hopefully somebody with some real-world experience will chime in.

 

Not going to take the computer off just get rid of the throttle body

 

Just curious why are you removing the tbi? Really no improvement in swapping to a carb.

 

A bypass regular is all you need for the fuel system.Set to 4-5 psi.
If keeping the computer, the charging system is covered.
The transmission will be fine.
I changed to carbs on my 88.
But agree,why the change?

 

The truck is running really rich and I'm not familiar with this trottle body so instead of changing one sensor after another trying to figure out which one it is I figured if someone made an adaptor plate it would be easy just to throw a carb on it and never worry about it again.But I haven't found one and if I have to change the intake it might be easier to change the sensors.I don't think it's the injectors the spray pattern looks OK and they're not cheap.Carbs are no brainers they always work and if you have a problem pull it off clean it up put it back on,no problem.

 

It might be easier to just find out what the issue is. Do you have any codes? What's the mileage? Cat and 02's in decent shape?

I'll have to check the codes again.Changed the O2 sensor last year and the Cat's not rattling and I have plenty of exhaust coming out.
