I have posted weights here and there but now I have an actual shipping scale instead of a bathroom scale, so odd shaped items are easier to weigh and I can get a more exact number.

The fiberglass bumper reinforcement in the 87-93 cars are closer to 15 pounds but I dont have an EXACT weight on this scale yet. Unless you mean the mount shock deals, they are pretty much if not the exact same and are pretty heavy for what they are.
 
Man don't get me started on weight again...lol


Hell speaking of which....what would be cool is to get a rear window from a coupe and one from a hatch and see what the weight difference is. While you're at it do the quarter glass of an '86 and prior coupe vs. hatch and '87+ coupe vs. hatch.
 
A couple 4.6L parts (02 4.6 SOHC):

Entire PI intake (factory) - 11.8 lbs - Compare that to 5.0L intakes in the 40-50 lb range.

Single head with cams/springs FULLY assembled: 44.4 lbs (both = 88.8 lbs)

Weighed on accurate digital scale subtracing body weight from body weight (+ car part).

Right but i'm pretty sure the rest of the engine makes up for the 4.6 vs. 5.0 weight...at least if we're talking about iron blocks.

I have had both a 5.0L block and 4.6L block. I wish I would have weighed them. I still got the 4.6 out, so maybe later...

I noticed no real difference.

The topend is lighter than a stock 5.0L, that's for sure.

The bottomend looks very similar, and I doubt enough to make the 5.0L be lighter, but that is just 'assumptions' right now. I do know the topend (heads, cam, and intake) is lighter.
 
Hmmm ... is that 18-pound hood a lift-off or bolt-on hood? If I were swapping hoods for the sake of weight reduction, I'd assume the lift-off would be a bit lighter, but I've always wondered just how much of a difference it would be. (If it's only like 5 lbs., heck, might as well pay the extra bucks for the bolt-on model.)

It's a lift off. They don't have a bolt on hood available. I think if you're going to spend money to reduce weight you may as well take off as much as possible.

It's difficult to find any fibreglass hoods in the stock shape.
 
No, 96-01 and 03/04 mach1 is aluminum, 96-98 being the strongest and maybe even stronger than the iron 03/04 cobra block.

Gotcha.

96-98 Cobra blocks were aluminum made by Teksid.

99/01's are aluminum.

The above had the hyper pistons.

The aluminum block is close to an 80lb difference.

03/04 Cobra uses iron block with forged piston/rod/crank with arp hardware.
 
I have a 302 shortblock out there I could weigh. I want to weigh a bare block though. The 4.6 block has to be heavier than a 302 block, I would think anyway. It's ALOT beefier. I can tell you an LT1 block is heavier for sure, trying to move them around is a pita. 302 stock roller blocks are made out of chewing gum and pansy flowers.
 
It would be great to see what the weight diff is.

With my center console and arm rest gone, and the e brake lever changed out... I bet I shaved 30#'s off.

I think all the weights of items in the car should be complied into one large list, and linked to in the tech thread index.... But im to lazy to do it right now lol.
 
Some info:

4.6-liter SOHC and DOHC
Aluminum block weight (bare): 86 lbs.
Iron block weight (bare): 154 lbs.
Assembled cylinder head weight: 44 lbs.*
Displacement: 4.6 liters/281 cubic inches
Bore: 3.552 inches
Stroke: 3.543 inches
Bore spacing: 3.937 inches
Main journal dia.: 2.657 inches
Rod journal dia.: 2.086 inches
Rod length: 5.933 inches
Deck height: 8.937 inches
*Assembled 302 iron head weighs approx. 55 lbs.

I know the beefier R302 block, if I recall weighs around 160lbs.
 
Good info on the 4.6 blocks. I have been contemplating picking up a cheap 96-98 GT and doing the PI **** and building a Teksid block motor on the side for it. Just gotta do more research. I really want another Fox Body though.

If I had this shipping scale before I got rid of this LT1 block a couple weeks ago, I could have weighed it just to see how it compares to the aftermarket 302 blocks since the GM stuff is known to be pretty beefy. I have a pair of Dart Iron Eagle 200cc SBC Heads and they weighed like 56 or 58 something on this scale with NO rockers. Thats a bit heavier than the E5 head I weighed but it's an aftermarket head with a pretty thick deck.

If I get some help over this week, I might toss the 302 shortblock up there. This scale is rated to 315 pounds, we will see how that goes.

This scale has been accurate so far compared to FedEx's scales.
