SBF weight?

SBF weight?
What would a small block Ford V-8 weight if it was all aluminum?
The 221, 260, 289, 302 family here, not the 351.
Aluminum block, water pump and front casting, heads, and intake?
How would it compare weight-wise to the little-bitty, "BOP", 215" aluminum V-8? And I figure that it can be B&S'd out to 300"s too...
But the Ford can go probably to 347"s...

Re: SBF weight?
Block length wise they're almost identical ..... there might be a 1/4" or so in it
The BO 215 / Rover V8 IIRC has a deck height of 9" or so
Thus with a std SBF at 8.2", all things being equal it would be lighter, but there's not much in it, in Aluminium
Not that I've messed with them much later but again IIRC the RV8 crank is heavier ...... however that may be a memory thing
The Ford heads are heavier, and the pump also unless you used the late style one
Like for like, £ / hp :
An Al SBF would easily outpower the RV8, again, weigh the same, but would cost a lot more
An Iron block (only) SBF would easily outpower the RV8, weigh more, but cost a lot less
If you could pick up an Al LS at the right money, that would make more sense if you're stuck on an Al block

Re: SBF weight?
Somewhere around 300-320 pounds. Been lightening mine up, haven't gone as far as aluminum block though. But the heads will take off around 45-50, intake I believe is around 18, block should be around 50. Water pump and the little things add up around 20 if I remember right.
Re: SBF weight?
Another old, "pdq67" story..
Years ago, I had a chance to buy a stripped out, 4-speed, '65 or so H/T Corvair that still had it's drive-train in it for $300. Body had all of its working glass and wasn't beat up. It was in a privately owned old, "boneyard"...
The owner asked me if I wanted to buy it.. Years later, he put an ad in the newspaper selling it for $300 to try to see if I would see the ad and buy it. I didn't have any place to put it or I still would have! I think the county got on his case and made him get rid of everything. Seems his Son was into weed and he got caught up in the Son's mess, and THEY searched his place and found a stack of un-turned-in vehicle titles and took them. He never finished the salvage end MO state's DOR paper work was all.
I would have bought it in a NY minute BUT I didn't have any where to store it.
I really wanted the drive-train out of it because even though it is say, "light-duty", that it would hold onna these little engines, The SBF and BOR v-8's Probably even a mild 265/283/301 SBC too?
Put this all in a F/G kit car for cheap using a, "Bucket T", frame with the Corvair front end on it and go have more fun than John Law will allow sorta deal is all.
In say a 1200 pound car..
Looking back, "woulda - shoulda - coulda", crap....

Re: SBF weight?
There are SBF 8.2" aluminum blocks that can be bored out to 4.185", and 3.500" stroke lightweight crankshafts, inline aluminum cylinder heads that flow 390+ cfm, and aluminum oil pans, etc. A 385 CI SBF that will make over 800 hp in a 302 size package. Several of those running around here with Cleveland style heads that flow much more, making more horsepower. Weigh less than 400# until you add vacuum pump, alternator, external oil pump, electric water pump, etc. Joe-71

Re: SBF weight?
I weighed a few thing of mine today:
E0 bare block, .040 over = 119 lb
D5 loaded head = 49.46 lb x 2
217.92 lb total
Aluminum, loaded head (2.02 x 1.6) = 28.94 x 2
Dart advertises their aluminum 8.2 ford block at 83 lb
140.88 lb total
That is a 77 lb weight savings.
As I remember, the installed weight of the original 289, w/alum WP, cast iron intake and exhaust, plus generator, was 476 lb. Take off 15 lb for the aluminum intake and at least 10 lb for a small alternator, that would put the SBF at just under 375 lb.
That redesigned, 302 cast iron WP is 20 lb more than the original aluminum WP. I also weighed that.
PS
That aluminum block, will cost you more than $100 per lb saved.

Re: SBF weight?
I'd say about 360. Iron block & aluminum heads is around 425 from what I see and the avg aluminum sbf block is about 60 lbs lighter than cast iron.

Re: SBF weight?

Too tall/wide for many applications.
