hi. i have a 1987 chrysler fifth avenue and was wondering what i can do to her to make more HP. Thanks

 

I'm going to guess that you are not subject to any emissions regs. since you are asking about this.

Put duals on the car, get a 4-barrel carb & intake, a 340 cam and valve springs. The trouble with the 5th ave. is the weight. That thing is heavy. I would probably look around for a set of gears, or rearend. That will make a huge difference.
