How to make 79' Ford F-100 faster?

I own a 1979 Ford F-100 Custom with a 2 barrel carbureted 347 crate engine installed in it. It currently has a 3 speed automatic in it, though i'm not sure if its the original or not. Being the 3rd owner, i'm also not positive whether the differential is the original or not… But id like to invest in getting it to get up and go quicker… Anyone have any suggestions or ideas on what i could possibly do? Ex. Supercharger, turbocharger, engine/trans/diff upgrades? Also if anyone knows what kind of diff might be in it?

Could needing an oil change cause the Service Engine Soon light to come on?

I have a 2000 Saturn SL2 and I've had it for about 2 years now. I bought it used from a good car dealerships. I have never had any issues with the car except a bad windshield wiper arm, that was fixed. I recently got the car fully tuned up in february. I was supposed to get an oil change at 160,300 miles, but I couldn't afford that change until now. I'm now at 170,280 miles. Could this over lack of an oil change have caused my "service engine soon" light to come on? And would it be anything MAJOR if it was just the "service engine soon" light and not the "check engine" light? I'm Really worried and starting to stress and I called a mechanic, who I'm waiting for a call back now.

How difficult is it to replace a clutch?

I never took any automotive classes or mechanical classes, but i'm a smart kid and have more common sense than most people i know and work with. If i take something apart i can put it back together…

i have a 2001 2.2L cavalier which is FWD… The clutch kit is $360 something, and the guy that is gonna put it in wants more than $700 plus tax. For that much money i want to take a shot at replacing it. I've ripped apart the whole interior of the Cavy to clean and try to fix up, i've replaced my brakes and rotors, and the radiator. I have a BMW 2002 with the interior and body panels stripped for restoring, but i haven't done any real engine, transmission, or suspension work on anything.

how difficult is it to replace the clutch and its components? Do i need any special tools besides the basics? And is it something i can start and finish in a day?

also, i talked to a friends dad that used to mod cars and drag race, and is currently restoring a '39 ford (i think. I don't know about the really old cars). He said, since ill already have everything torn out, to take the flywheel out and get it resurfaced because since the clutch has been slipping for a few months, it would have created "hot spots" on the flywheel, which should be taken care of. Any opinions on that?

thanks for any help or tips. I learned to drive stick with this car at 50,000 miles, and i got it at 60k. So another 50k miles with occasionally taking it to the redline, downshifting and throttle blipping, and a burnout here and there, plus teaching a few of my friends stick, i'm very pleased it lasted this long. Oh and stupid question- is there a break in period for the new clutch, or is it get in and go?

Should I buy a Ford or Chevy van?

I need a van to carry around my band equipment with, and my budget is around 4 or 5 grand. I decided to go with a used conversion van since they are cheap and like the high top, and I can easily take out the unnecessary stuff like the bed and tv. But that brings me to my current dilemma. Ford or Chevy? I've already pretty much ruled out dodge. From what I've found, a Chevy g20 van would have a lot of room for my stuff and would probably be perfect for me. But I always hear that ford vans are tougher, last longer, and are better for towing. Every ford conversion van I've seen has looked smaller on the interior than a Chevy, so I guess it's a bit of a trade off. What do you think?

By the way, I'd rather not have to pull a trailer if I don't have to, so don't start telling me to just buy a trailer for my stuff.
