I think you have answered your own question... Silly money. In fact at that price, I would say drug-induced dream world. I'm sure you could pick up an ACT carbon fibre plenum wth throttle bodies for around that price. However, if it sells at that price, I know what I'm going to start buying!I haven't tried them myself, but I'm sure I read a thread a month or so ago from somebody with a good degree of experience, who said they tested a modded RV8 twin plenum on the dyno, and there was no difference in HP. The size of the plenum is more important from what I understand, which is why the ACT carbon fibre twin has a different trumpet base. The addition throttle body apparently makes for a smoother pick-up of revs.
I could of course be totally wrong, however,if you feel like blowing some spondoolies, I'm happy to mig you one together for £950!

I would of thought something like no more than £200 for that .I haven't tried them myself, but I'm sure I read a thread a month or so ago from somebody with a good degree of experience, who said they tested a modded RV8 twin plenum on the dyno, and there was no difference in HP.

I once travelled 150 miles and paid $350 for a 'six pack' manifold for my father's 409 powered 1964 Impala SS convertible.
Yes; that really is a 409 as in the Beach Boys "she's so fine my 409", in a Chevrolet Impala SS convertible.
Point is; there was no way on God's green earth that the original six pack (3 x 2 barrel down draft carburettors) would ever make as many horses as an aftermarket Holley manifold and 4 barrel 750-800 cfm carburettor.
It isn't always about power. Sometimes it's about kudos / originality / rarity value.
I can assure you that the man who eventually bought that car from my father is very appreciative of my efforts. Thirty-five years later, he is still running that set up, and proud of it.

Mmmm a BB Chevy with a six pack Yes; that really is a 409 as in the Beach Boys "she's so fine my 409", in a Chevrolet Impala SS convertible.

always facintaed me this I know it works but GM should of bunged another 2 barrel in there to make it a carb per cylinder
probably bulkhead and dizzy limitations I would imagine
I went out in a stock factory manual (stick shift) 67 Nova SS 350 once
but also got to drive a modded 66 with a 454 auto
blimey no wonder my Bro-In-Law swears by BB's

The wiki doesn't mention the six pack, though the one I bought did have GM markings and part number, but there was a dual 4 barrel option as well.
Those damned Rochester and Carter carburettors would have been absolute Hell to tune compared to a Holley (I know as I had a couple of Rochesters).
From a technical standpoint the first generation BBCs would be slightly more useful than a boat anchor by comparison now, but again; it's the kudos / originality / rarity value in having one.
I always swore by the BBC. To get 500+ hp out of one was child's play and the result, even in a full bodied Yank mid-size, is an amazing driving experience.

Actually, the 409 (along with 348 and 427 versions) was the first generation BBC see the wiki, and drastically different from the version I grew up with, and which the modern versions are based upon.

the Pop above was powered by a crate LS7 (manual BB Corvette NOS) (thats the original LS7 rather than the late) factory GM solid/mechanical cam no auto option came with a flywheel and IIRC intakes and valves that were huge topped off with a Dominator carb that was not factory though
sorry chaps back on topic
I could talk about American muscle car stuff till the cows come home
