Re: Hard to lose weight!

Put the car on the scales today, and despite the increase weight with the T56 and bellhousing, I only went up 5 lbs. So, all those little places to reduce weight were enough to pretty much break even.

3806 lbs with a full tank and a better center of gravity.

So the t56 magnum only added 5 pounds after all is said and done?
Or did you do some of those weight reductions when swapping to the t56?
I'm hoping it weighs less than my th400/converter/cooler/lines.
I will be using a 30lb fly wheel and a QuickTime housing

I did a bunch of weight reductions. flywheel and clutch. driveshaft. Removed stereo. Sound deadener. My console plate. Removing unnecessary wires. Mini starter. I believe the hydraulic clutch setup weighs less than the mechanical too.

Oh I see. How much did your old flywheel weigh?
I'll be using a 28lb billet... I assume the clutch and flywheel in my case will weigh less than a torque converter.
I will be swapping to an aluminum radiator(hopeful for some weight savings). I didn't realize that you did all that at the same time. That's crazy!
I know I could save a good 100lbs with removing power windows and door locks but I want to keep it as a fun street car. I'm looking at header wrap vs ceramic coating just for heat purposes in the engine bay. I know the header wrap is horrible for headers but I just want to her rid of the heat

Mid 80's Blazers had the plastic tanks/alum core rad. Uber light weight. Fits Chevelles like a glove.

Re: Hard to lose weight!

Tried an on-line search for hollow and aluminum bolts with no luck.
The keyword algorithms have gotten so bad that no matter what you try to find all you get are unrelated Amazon links.

I no longer have my EDM machine to make my own hollow bolts so will have to buy them.
Anyone have a good source?

If I have to I can still make aluminum bolts on my lathe but lose out on any heat-treat for toughness.
Anyone have a good source?

At these gas prices I want it 100+ octane, leaded, and my windshield washed!

Re: Hard to lose weight!

One of the guys on the Mopar thread is buying surplus titanium bolts for cheap prices. Titanium weighs 1/2 of what steel does, and is stronger from what I hear.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Titanium is very light but also very brittle.

No one makes bolts out of titanium.

It is too expensive and doesn't have the clamping power of alloy steel.

a big negative on the TH400 weight.


You will gain weight with a manual


TH400 long tail with 10" convertor and fluid weighted 165lbs


T56 magnum 135lbs, bell housing 25lbs, flywheel clutch combo 45lbs minimum, and hydraulics/brackets will be another 10lbs.


posted this a while back somewhere, don't remember where. a 4spd with a gear venders would put you ahead in the weight game vs a th400 auto. especially considerings McLeod racing makes a SFI rated aluminum bellhousing weighing less than half of the steel counterpart.

Back in 1968, factory ordered Oldsmobile 88 police cars came with titanium wheel studs. I got a bunch of them from a local dealership when Oldsmobile discontinued them. It may be rare and super expensive, but they are used frequently in military and aviation.

Surplus and out of specs titanium bolts go for cheap on secondary markets. Had a friend that worked for a machine shop that made titanium bolts for the military. After the contract ended, they scrapped all the titanium rod that was left. It replaced a lot of steel on race cars that were built in our shop.

Re: Hard to lose weight!

Ti is funny stuff.
Strong and light but not good for rubbing surfaces.
Has some issues with machining due to work hardening and chip flame-ability.
Ti lug nuts are pretty available and appear to work fine.
Never saw Ti wheel studs for sale.
Biggest issue is price and availability in sizes needed to assemble a Chevelle.

I think the simplest means to lighten bolts is to cut them down to exact minimum length.
Many are way longer than necessary.
Second is to get them in hollow form, or modify them to be hollow.
Poking around the web it seems there may be some Carbon Fiber nuts available but after working with CF pretty extensively at a former job I'm skeptical of them for automotive assembly.
I will make a list of sources as I find them for lighter fasteners.
For some things even plastic screws can work, aluminum should be fine for many more.
Not going to save a hundred pounds here but anything to off-set the roll-bar and frame braces will help.

Re: Hard to lose weight!

Cutting down lengthy bolts can actually save quite a bit of weight.

They carry Ti wheel studs and any kind of bolt, stud, nut, washer you want.
