Because for the same $$ it takes to build a 466 SBF, you'd have a 557" BB..
Weight isn't that big of a deal, 260LBS more.. less with aluminum heads. BTW, the stock 4290/460 block is good to around 800 HP
I've seen a few pushed quite further than that, especially with a 4-bolt main conversion.
Not to mention the motorsport blocks . . .
I think BBF in Foxes are cool, but plan on spending WAY more money than what you would a Windsor, and with MUCH less options on combos, too.

Less options in what way? It all depends on your goals too. A 700HP BB is going to be cheaper than a 700HP SB. If you're looking for450HP, then the SB is the way to go.

Yeah, I know of a certain promod that ran into the 6's with a stock block with the conversion. I have the engine systems main caps, They're BEEFY!
Them compared to a the stock 460 front cap..

love the big block.D&D automotive sells a complete kit for the swap. Any 4cyl or 5.0 k member works.The Mustang Depot has all the rebuild components for a decent price. I think the power brake booster is fine in your car.I believe the maximum dia. booster that fits is 7 or 8 inches,smaller the better. With aluminum heads and intake your at the same weight as a stock 351w. Had a 429 in a '78 Fairmont I once had,even kept the stock flat hood. Used stock height 302 with air coil springs.Killer low end torque. Couldn't keep tires long enough. Great swap,lots of fun. Had almost 480 hp and almost a dead stock idle,not tempermental, no exotic stuff,no over heating, just start it up and drive. Grandma could drive it for groceries,stop for gas and drive it back home.
well.. we're going to see how the BB does.. started tearing it down this week. and going to send it off to the machine shop to have everything checked over.
like 7upstang said planning for 500-600 on motor and then i'll decide how much to spray on top of that.

hey buddy.. nice to see you.
please tell me you have the answers to all my problems.. i'm thinking about going turbo now. check my thread in the gen chat on LR
i'm trying to figure out if the block i have will handle the power from a turbo. i'd definitely wanna turn the boost up eventually and make some serious power with it.

429/460's are the way to go if you want some serious power. I've built plenty of them. Check my link below.

I've built a naturally aspired 460 truck block with std size 460 forged pistons,std size 460 forged rods, and standard size 460 forged crank with main girdle that put out 720 hp on a engine dyno. If you want to throw boost at it and make more power than this I would recommend a Ford Racing Block.
this is what i'm trying to figure out cause i might put a turbo on it. if not a turbo then it is definitely going to see some spray
I am building a similar motor right now . . .
466
waiting on my probe pistons to show up! its been almost two months
Eagle SIR i-beams
pp balancer (got the rods/balancer for $150, don't ask
)D3 heads that I ported and put the 351c 4v valves in (2.19/1.74)
241/249 voodoo cam
torker II
850 race demon
I hope this thing makes 450 or so rwhp (th400) and I will be spraying 200-250. Or whatever it takes to get in the 5s 1/8
Personally for a dirt cheap build I would do a BBC/th400 with a motor plate but I got the rods and balancer for a song and picked up the '73 long block from a friend of mine for $80. Besides a ford in a ford sounds better.
I split my sbf block with a turbo awhile back and was never happy with the carb I converted to blow-thru. I also had a steep learning curve with the BRPV and felt that I could have been racing a LONG time ago had I done a nitrous combo.
