I have recieved some conflicting advice on whether or not these manifolds are as good as advertised, and could anyone with experience with them let me know if they would be better than a Weiand X-elerator in the 2000-6500 RPM range on a warm 302 cleveland in an XD Falcon ?
Specs are: 302C, Crane H-288 CAM, Crane Roller rockers, springs etc. 650DP Holley, Pacemaker extractors, 3 inch single system, shift kitted C4 with 2200 stall converter, 2.92 Bw 78 Rear end.
This manifold is only good for engines between 4500-8500rpm.
It would look good but it will be a waste of your money.
The guy I know use's them on circuit racing engines,with 12-14.1comp,265+@.050cams etc

I think the FW will be way too big for yoour combo, especially with a 2.92 rear end. The FW is a high rpm manifold and you are running a small -ish cam
all in conjunction with a 302c. Your motor will rev to 6500 but it will be needless as it won't be making much more power than 5500 for a lot of wear and tear on the motor. I would *almost* be tempted to put a performer on it.
I would be saving up for a 351 conversion first, then a better diff ratio (3.25 + ) and things would start to work better.
Thanks for the advice, I will probably go with the 2V Weiand instead.
and get a better diff setup as well.
Once again thanks for the help

Nismo_Capri has already seen some of these.
Just follow the link below to my half baked website (Sorry it was a Quikie)
I have been looking at getting a funnelweb, but it needs a hole cut in the bonnet, apart from that, they seem to be a great manifold, for high revs, and a big cam.

I was just about to look at a new manifold as my engine wasnt showing the power it should, but ive since found it has spun a conrod bearing :( so, back to the drawing board.
HOON DOG if you can wait till later this year i'll have a weiand x-cellerator for sale cheap... But it'll take me till then to save for the mods I have planned.
I've been discussing these issues specific with Terry Parker directly for my application as well.
His advice to me is that the 2v Funnelweb will still eat the Weiand for performance, even at lower - mid revs, contrary what these others are saying here.
Just who knows?
Either way he's a friendly bloke, and his advice seems pretty convincing to me, so why not ask him yourself. E-mial address is: parkerracing@itfusion.com.au
Tell me about it, ive waited 2 months for the top end rebuild, only to have the bottom end go bad, ohh well, on the bright side, i can have the deck height lowered now, more compression, and more flow :)
should be going by spring ?.

Really depends whether you want under bonnet or not. You can't really compare a 5" high single plane manifold to a 7.25" high, high rise manifold like the funnel web is.
I'd personally compare the funnel web to a TFC which is the same height. The TFC has been proven to out do the FW. TFC's are becoming a more and more common high rise manifold for clevo's. Especially at the strip.
The whole idea of a high rise manifold is to increase windspeed on engines that don't have any or have minimal due to large cams or low ci.
