Which driveline combo do you think would weigh less???

Just thinking here. Which do you think would weight less.


An 351 fuel injected setup with Al heads, Cobra intake and all other relataed fuel injectior gizmos with a T-56. No smog pump, A/C or P/S

Or

A 96-98 Cobra Alumunum block/headed 4.6L DOHC with a T-56?? No A/C but P/S would remain to run hydroboosted brakes. Also, would be installed with aftermarket k-member for 4.6L engine


Think it's close enough not to really matter?

the cobra engine would be cool.

I guess you could find the dry weights of the engine combos, and find what each transmission weighs...

T5's weigh around 80lbs I believe...

I'm sure D&D would know the weight of a t56, which would be more...

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.

I think the 4.6 DOHC will be lighter

hot rod magazine featured a fox with a 98 cobra motor in it this month. It listed everything that was needed along with brake upgrades and stuff. I would pick it up if you are thinking about doing it
