Anything bolt on from eBay would be a waste of money. There are web sites showing the scams...fuel ionizer, tornado intake, pills in the gas, etc...

Learn how to tune it and work from there. Change to an electric fan, CAI intake works on some cars, exhaust change, possibly underdrive pulleys you'll probably have to find some yourself. There are a lot of minor things that can add up. The real fix would be rebuilding the engine with more compression and a better cam.

carb spacer, CAI, exhuast, replace old ground wires, better ignition. But you should go for a better cam like zonie said, best bang for your buck

Yeah, but where do you find a hotter cam for a 1980 Cadillac 6.0 Liter?

Make sure its running right. Make sure the carb is properly adjusted and clean, change spark plugs, seafoam all the carbon buildup out of the motor, change the rotor and cap on the distributor, flush coolant, change the air filter, change the pvc valve(if it has one), replace the accesory belt.

Other than that, maybe put a less restrictive muffler on there. I wouldn't waste money on performance parts for that motor, the compression was low to pass smog, not a lot of cubic inches, its a smog era motor, best bet is to swap it out to a built 500ci Cadillac motor and gain about 300 horsepower that way.

Speed costs money. How fast do you wanna go? Aron is right. You would spent more money trying to make a 6 liter faster than if you spent $250 at the junkyard swapping in a 500 or 472.

And with prices like that, the cubic inch to dollar ratio is insane!

dudes... Im not trying to take it on a quarter mile...

I just want to make my engine run smoother and gain some acceleration. My car has gone quite sluggish.

I will definately take some of the suggestions above... But like, what is that rusty ass thing called on top of the carburetor? What about a new one of those?

That rusty thing on top of the carb is the air filter housing.

Ok, you want it to run better. Here's what to do to get it running the best possible without doing any "mods" on it:

- correct air pressure in tires
- make sure brakes aren't dragging (check slider pins on front calipers, check to make sure rear drums are rotating freely)
- air filter
- PCV valve
- breather filter
- spark plugs
- spark plug wires
- cap, rotor
- coil
- set timing
- adjust choke
- switch to fresh synthetic oil and good filter
- flush/fill coolant, new thermostat
- make sure heat stove is opening
- make sure exhaust heat crossover is working
- replace catalytic convertor

You don't have to do everything, but all will make a difference. One important point, though: if that cat is plugged, it will make a HUGE difference. If it is the original one under there, I would change it. New cat designs are much more efficient than the old type.

all that should be under $200 depending on the exhaust and you will love your Cadillac. And dont delete your catalytic converter, get a new one. You will have more torque depending on who you ask.

Hey thanks guys... thats what im talking about... i think I have a new catalytic converter but could i buy a flowmaster one from ebay and put it on myself? how hard would that be? and what gains would I get?

putting on exhaust depends on how rusty your old stuff is. If its really rusty, prepare to cut it off. Putting on new stuff can be bolt on if done right but the old stuff is not fun. Exhaust can be easy to do if its after the manifolds(the parts connected directly to the motor) and really easy after the converter. If you get a flowmaster muffler, you should feel the difference mainly on the highway. 45mph and up should be better, and the sound of course.

If you don't have emissions testing in your state, you can hollow out the cat. That's a definite cost saver.
