Hi there, I recently just got a Corvette. Here are the specs.

1994
54,000 miles
6-speed tranny
Convertible
Bright aqua blue metallic
Black interior
Black top

The car is 100% stock and I am SURE it has the stock wires and plugs in it. I have a set of AC delco plugs that I can use that have been in my garage since my friend sold his 94 Corvette, he never used them but they are new. I want to get wires but am afraid of which ones to get after the horror stories I just saw of the MSD and a few other types of wires.

So what wires are of good quality but will also not be a pain in the A$$ to change? Also, what gears does this car have in the rear and what gears would you folks say would be a good all around gear? I was thinking 3.73's or 4.10s with it having such a tall 6th gear.

Thanks!

 

I installed some Taylor 8mm wires this past spring and am happy with them. Previously I had tried an OEM set, but they didn't fit as well (not all the same length as originals). Whatever you buy will be a PITA to install ;-)

4.10's seem to be a very popular mod for 6-speed cars.

 

Well I am going to change my wires really soon....as within the next week, have to price the gears, dont really want to spend a boat load of cash, just want a little more performance.

 

I put GM wires on mine. They fit the looms and lengths were close.

 

i used msd wires on my 88 3 years ago, what horror stories about a set of plug wires? dont over react they are just plug wires. No one can tell the difference between the cheapest and most expensive wires on a car.

 

Just going by people saying they are long, or short, or dont fit right.....thats all.

Not sure which ones I am going with, I need to change them on my dads 93 vette as well.

 

I had Taylor wires on mine. Can't remember where I got them, but picked them up with some NGK plugs from a forum vendor for not very much. The quality was great compared to some other brands I've seen.

You can check your RPO codes for what gears you have from the factory. I had 3.07s in my '95 A4. Most popular gear for an M6 has got to be the 4.10s already mentioned.

 

AC Delco PN 708W

 

Thanks! Now I have to figure out what my rear gear ratio is. Someone told me they should be 3.45 but not sure. I know the car could use a lot more....lol

 

If it is a 6 speed the ratio is 3.45 unless someone changed it, general opinion seems to be 4.10's are perfect for a manual trans LT1.

 

This is from a forum thread:

As mentioned before, you can simply check your RPO code, unless someone has changed the gears out.

 

You guys rock!

 

do headers while doing plugs, and wires and add 4.11's

 

Ok......what is the price of all this crap? lol

I was looking at the complete LT4 hotcam kit with heads and air gap intake.....but with going to college it would be pretty tough.

 

If $$$ is tight, just do the wires. I got my Taylor 8MM from Summit (summitracing.com)
Replace the plugs with what you have - the AC/Delco are fine.
Get a gasket kit from NAPA for all the gaskets in the Throttle body. I'll update with the part number when I get home. Take the TB off and clean everything!
That will get you a basic tuneup on the LT1.

Gears, IIRC you are looking at around $2k with labor.
Headers, for the most part you are looking in the $2k+ range with labor since the exhaust shop will need to graft them together with your exhaust. If you do a full exhaust and do it yourself you are around $2500.

Anything else is $$$, check Loyyd Elliot's site for porting heads, intake and a matching cam. He has been doing it for a while. IIRC a setup I was looking at was around $3K.

If I was going to school I'd do the basic tuneup and plan what my targets are for the car. Then read, read, read, start accumulating the parts to reach my goals.

 

Gears around NJ are about 800 bucks all parts included , install kit,gears etc, and removing and dropping off the center section.Of course reinstalling the center section yourself.

 

I will order the wires this week. The car has not been driven a lot in the last year or so and I think the gas was a little bad in it. I have ran it about 500 miles in 2 weeks and a few tanks of high test in it along with some fuel injector cleaner and it seemed to help A TON. I think the wires and the plugs will help even more, along with what you said in regards to the gaskets and the TB needing cleaned.

This car is something more than just a car to me. It is going to be my means of paying for college if I end up short on cash. Hopefully that doesnt happen as I really like the car.

I was talking to my girl friend last night and told her that I wanted the head/cam/intake package, 4.10 gears, and exhaust and she said "What about paying for college?" and I mentioned that I just sold one bike and that I could sell the other and it would cover the modifications. She about stared a hole in me and said "We are NOT selling our bike....I want to ride motorcyel and the car is fast enough." Silly girl doesnt realize how addicting power is....lol I think she is correct though, I would rather have a Corvette and a bike than just a faster Corvette....well maybe not.

I have a guy that did the gears in my camaro for $150 and they were perfect. He does a lot of rear ends and is an old dirt track racer from the 70s. He also builds engines. He has done 2 for my dad and 2 for me already and each was a screamer.

Where are you getting the gears from?

 

I went with Moroso Blue Max wires on my son's 96 a couple of months ago. I went with 8mm so they'd still fit in the factory wire looms, thus keeping the wires away for the exhaust, etc. Perfect fit.

Choose wire that are a specifically designed for your engine, not the universal ones where you have to attach the ends; makes for a tighter, leak-free connection.

I bought a book written by owner of JACOBS Ignitions, a PhD in engine ignition systems, who wrote that the plug wire resistance issue you read about so often is nothing more than advertising hype. It means little and shouldn't be the criteria on selecting which wires of buy.

One more thing - if you are having driveability problems look at the sticky posts above by FIC Injectors. If your injectors do not ohm out correctly call Jon at FIC and get injectors from him. On an LT1 they are real easy to change.

Also you may want to change the fuel filter.

 

Run a bottle of Chevron Techron or Sea Foam through your gas to help clean up any varnish from the old gas.
