1974 Plymouth Duster 318 base (Yellow Duster)

Last updated Aug 6, 2015  

Photo of a 1974 Plymouth Duster 318 base (Yellow Duster)


I found this Duster for sale in a shed in Colorado that was pretty much stripped bare, down the metal. It was a project that the previous owner lost interest. The Duster is in really good condition for its age, it only had one cancer spot about the size of a quarter, easy fix.
It came with a 318 motor but I've decided to put the 360 from the 88' ram in it instead, the 360 is going to be modified quite a bit, I'm also going to put a Torqueflite A999 (beefed up 904) from a former cop car (Dodge Diplomat) in it as well after a rebuild and shift kit installation.
This is currently a work in progress.


1990 roller cammed 360 cu
Estimated 380+ hp when finished.
3.21 to gear ratio.

Lower geared torqueflite A999 transmission with TF-2 shift kit.
1990 roller cammed 360 cu.

Magnum Air Gap Dual Plane Aluminum Intake Manifold with Edelbrock 650 AVS.
Cleaned up and milled mopar 308 swirl port heads.
Hooker Headers with dual 2 1/2" magnaflow mufflers.
I am going to switch to aluminum magnum cylinder heads later when I have more cash which will bump the compression to around 10+ to 1.

Will also change out the camshaft soon as well, so it can idle better
