As the title says, is it true?
i find that hard to believe:hide:

IF you use a eldebrock aluminum intake manifold

IIRC a BB Cad is about 600lbs. The stock intake manifold is 45lbs, the Edelbrock is 22lbs lighter.

I heard there is a high amount of nickle alloy in the BB Cad's that make it a very strong engine/resistant to wear.

I have read from several sources that a caddy 472/500 weighs 600 lbs, a SBC is 575, and a BBC is 680. Well, after wrestling with 3 engines this past weekend I am not so sure. My friend and I trailered a chevy 4.3, a chevy 350, for him and a '69 caddy 472 for me. Loading and unloading the 4.3 was cake, the 305 wasn't bad, but after stepping on my nuts heaving the 472 around, I question that 600 lb #. I don't know If we were intimidated by the sheer size of it, or it really is a lot more than 25 lbs heavier than a small block.

So I weighed it.
Complete '69 472 air cleaner to oil pan, fan to flexplate. All weights are in lbs. and include the bolts, etc. for that part.

Block-------------------------------------------- 210
Crank w/hub--------------------------------------78
pistons/rods,bearings---------------------------- 30
Heads w/valves, springs----------------------- 125
valvetrain-Cam,lifters,pushrods,rockers,chain,gears- 27
cast iron intake ---------------------------------- 43
oil pan,pump,pickup---------------------------- 14
valve covers---------------------------------------- 7
water pump, plate---------------------------------10
flexplate--------------------------------------------- 5
fuel pump-------------------------------------------- 2
motor mounts----------------------------------------7
distributor, coil, wires-------------------------------7
exhaust manifolds---------------------------------- 31
balancer, pulleys,brackets, belts-------------------15
alternator-------------------------------------------- 10
power steering pump-------------------------------14
air pump------------------------------------------- --10
cooling fan---------------------------------------------6
Q-jet carburetor,dashpot,choke spring------------10
Air cleaner-------------------------------------------- 5

Total--------------------------------------------- 666 lbs.

there was no A/C compressor

ready to run- carb to pan,w.p., cast iron exh. manifolds- 599 lbs.

use alum intake (368-- 17lbs)------------------- 573 lbs.

take off exh. manifolds ------------------------- 542 lbs.

Hmmm, looks like I will have to weigh a SBC to compare them in the same state of dress.

Ted In Olympia Replied:

Thanks for the info but I'm confused. How did you get from 666 to 599 pounds?

Thanks for the information and hard work. Neat stuff.

nytrus1 then sent this message:

599 lbs. is without any front accesories, motor mounts or air cleaner.

666 lbs. is complete, just as it came out of the car.

A few days later Nytrus 1 added this:

finally got a chance to compare weight with a SBC 350 4-bolt main. As I suspected, the caddy 472/500 weighs considerably more than a SBC 350.

I weighed the SBC the same way as the caddy.


Caddy SBC
************************************************** ****************
short block--- 318 240

long block------- 475 365

ready to run w/cast iron intake -- 599 493

with aluminum intake-- 573 477

complete as pulled from car --- 666 549


100+ lbs. difference!!!

So, in complete trim, the caddy is 66 lbs. heavier than published and the sbc is
26 lbs. lighter, although in as ready to run trim, my weight measurement matches what Al (MTS) has listed on his website.
...

From the other board. So it's realistically about 100 pounds heavier, I'd definately take 100 more pounds for 150 more cubes.

I would like to see a comparison to the 454 or even 460. Be a bit better apples to apples comparison.
