I'm not sure where I should start, I suppose the air filter. One of those chrome Edelbrock ones, then swap the filter for a K&N. I assume one size fits all on those chrome filters? And is it as efficient as a cold air intake tube like on rice burners?

I read about cutting the brown wire to bypass the feedback solenoid? What does a feedback solenoid even do? I would rather put an override switch on my dash because it says overriding it decreases your gas MPG really bad.

It needs some pickup, it's a little laggy I already did a tune-up. It almost seems like a gearing thing, if I step on it I think I need to be at the beginning of a gear to feel it or something. It's a 1988 with 71K

I like the idea of using a 500 cfm Edelbrock Performer 4 barrel carb with a 2 barrel to 4 barrel adapter I heard about. But what would that do to my engine as far as risking blowing something? Sounds like you would need to be a carb guy to tune it correctly to this engine.

Then there is the idea of supercharging it with some sort of mini blower off a Thunderbird or something??

Maybe my best bang for my buck would be sandblasting the inside of the intake a little larger or opening up the intake holes a little bit?

Ideas people :1237:

I was thinking the same thing, probably would have the same gas mileage by the time I was finished with all the V6 mods.

holy shit man u havr a million ideas going lol like bogie said v8 prolly be the tbi setup for tgat year or you can go the way i did thays the best bang for your buck i would nt waist my time with your v6 man

a mild LA 318 would be nice and it should get around or better mpg.

Just FYI, i get almost 20mpg on the highway and about 13 straight city with my stock (plus headers) 318......

Well my ultimate plan was to put a 318 in it eventually but until then there's gotta be a little something. Obviously air and I am really curious about what bypassing the feedback solenoid is doing?? Basically since the motor only has 71k original miles I might as well beat on it for a while and put my money into the suspension and body for now.

When the time comes, I would rather use a 92-96 Magnum if I do the V8 transplant. How much more complicated is this to do besides dropping my mechanical fan for a slim electric fan?

Hmm I wonder what I am getting now with my 3.9 or should be getting.

ull need a wiring harness flexplate torque converter unless u go 5 speed and ull need the motor and prolly more im forgeting

I planned on grabbing all the wiring, and when I do the swap I will be getting a manual transmission at the same time. I don't want to fuck with a dead engine at a junkyard so I may end up buying a whole truck off craigslist or something then swapping the motors and selling the 92-96 truck with the carbed 3.9L in it so I can make my money back. The engine mounts drop right into the same places on a 318 Magnum as a 3.9 LA?

 

[slade]

idk my la 318 the mounts are diff i had to make my own for it

 

[pinkfloydeffect]

So I have been thinking this through, and I will definitely be doing a 318 swap "eventually" but since I only have 72k on my 3.9L I plan on getting some miles out of it while I put my attention and money into the body, chassis/drive train, interior etc. In the meantime which will be at least a year or two I plan on driving the 3.9L so I was wondering if anyone makes an aftermarket cam for them since I have to install a new radiator anyway I think I can do the cam while its out without having to take the block out. I know it's only a V6 but I want the choppy sound/idle, I do not know much about cam styles my buddie suggested a "mild" cam for the sound I desire. Anyone??
