Hey guys! I just inherited my grandpas 1990 dodge d150 4 speed automatic 318. I am wanting to get some power out of this mean machine! What are some suggestions that you guys have that I could do. I’m really not to worried about looks I kinda want it to be a sleeper! Any advice would be great!
So far I’ve deleted emissions stuff as well as got rid of the a/c.

 

This might fit under the hood!🙂

 

If that's not in your budget a stroker kit for your 318 would get you off to a good start.

 

Haha I wish it was in my budget! Thanks for advice!

 

Probably the best way to pick up some performance is to find out what gears you have in the rear axle. There should be a build decal under the bottom side of the hood that tells you axle gear ratio. There should be a tag on the diff cover also, let us know what you have.

 

Just looking at the photos, that is not a bad looking truck for its age. I would save up and big block it or find a wrecked pick-up with a hemi and swap the whole powertrain. You really didn't gain much deleting the A/C.

 

yeah, i just deleted the ac becuase it didn't work anyway. From what i read you don't really want to sleep on the 318 even though its a small block. A hemi swap would be awesome though!

 

The 318 is a stout and very underestimated little engine. That being said, if you can stroke yours or do a big block swap, go for it! Still, if the thing runs well now, a little thumper cam and headers might just wake that sumgun up! (if it were me, I’d go with the type that allowed for an o2 sensor so everything stays happy).
