Pull the cover and inspect the rear before you condemn it.

If you aren't changing gears, I would almost guarantee re-using the shim configuration in there now will get you right where you need to...

This looks like 1/4" NPT to me, but given the scale I suppose it could be 1/8.

Many years ago I was looking for one of the factory air dams and couldn't find one. I ended up having a local fab shop bend me one out of aluminum, but I never installed it (was intended for the red...

This is critical advice.

Roller cam = steel gear

Flat tappet = iron

There are also composite and bronze gears available, but they are usually race spec only.

I believe there is an...

Update! I still have this car! I had big plans to race it, but then the Vid hit! I have pretty much returned it to stock, sold off the parts and just go for rides here and there on weekends with...

Just updating some threads and wanted to add some newer pictures.

The GM has been a great car for me, just turned over 92,000 miles. The exhaust is still too loud, but I like it just the same.

I did the Dorman swap on my '08 car, but did not have it long thereafter, so I can't speak to the longevity of those parts.

I do know that the long bolt on the t stat housing snapped off in the...

Not sure how I ever missed this thread. I have always loved the 2 door sedan Fairmonts, but they sure are hard to find.

Interestingly, there is a guy here in CT that has a pale yellow Futura with...

$5K is absurd for that car. On the high end I would expect to pay 2000-2500; he is out to lunch. Honestly the body rust is enough to turn me off. I purchased a pristine (and I mean pristine) '06...

This thing looks to be incredibly clean underneath! Always a NY car?

Alot of good points here.

I will echo the sentiments of others. I bought an '06 GM last December and the EATC defaulted to defrost within 6 months. $3 in o rings and about a half hour of my...

One time I thought it would be a grand idea to restore a late 70s Ariens snow thrower. The old machines are "unbeatable". Procured a decent used one and went through it; the only mechanical issue...

Gears are the biggest obstacle for you; whether you decide to supercharge or not, its the first place to start. They will make more practical use of the cars current power through torque...

I would be worried about the dash pad ending up in my lap when I was properly launching and powershifting that 5 speed...

Recently replaced the brakes on the car (rotors were original), and noticed that the upper ball joint boots were ripped. They are still "tight", but UCAs, LBJs and tie rod ends are en route today. ...

Preservation!

Lately I have found that I am itching for another truck project. Unfortunately for me the dentsides have gone wild in price over the past 18 months. :(

Soon though. I miss a...

He's not active on here anymore, but mrltd's Country Squire was an autocross savage with a much milder build; actually mostly stock parts.

Just a thought, I put a brass valve in my heater core feed hose. I left it closed most of the time unless I knew I needed heat/ defrost. I spent a lot of time at or near the 6250 limiter without an...

Magnaflow 2.5" offset on my 4.6 with no downstream cats. It is a custom bent 2.5" cat back with a crossover.

I hate it, the drone makes the car really annoying to drive on the highway. When I...

You've done an incredible job on this! What cruiser for you and the family to enjoy!

See how I mounted my stacked plate cooler and ran the lines in post #34.

Automatic transmissions aren't my bag, but the AOD in my white coupe was pretty decent. It was a basic rebuild with upgraded clutches and an A+ servo, Silverfox SPT-R (OD lockout), B&M deep pan,...

With that intake and 165s, you would be fine with a factory HO cam. Excellent drivability and a significant power improvement. Rocket arm ratio is usually spec'd to a specific cam, like Phil said....

That sucks the tranny is noisy. T5s are a fairly simple beast in my experience, and no doubt in your wheelhouse.

If you have to rebuild... whether you plan to run it hard or not, the steel...

I think the Detroit true trac is decent; nowhere near as clunky as the original DL.

I have a 2012 Boss 302 with a factory "torsen" diff (31 spline); not sure if they are available over the counter...
