Pics of new W heads

[mac1]

I was at the Good Guys show in Costa Mesa Ca. today and took some pictures of a high po head and a low po intake at the Edelbrock trailer. They said the complete heads should be around $2200.00, but the price hasn't been set yet. They also said they were coming out with single quad intakes for the hi and lo po heads next year. Mac

They look GOOD... REAL good:cool:
Manifold is nice... hope it has clearance to the lower edge of the valve cover ?
looks pretty close.

The single quad intake.
what surprise:rolleyes:
Yeah, I heard about it last week:grumble:

Hey Bob ( Walla ).... Region Rat...
Looks like I'll be right there beside you:coffee:

How come the heads have the bolt holes between the intake ports and the intake manifold does not ?? :dunno The bowls do look improved from regular 690s. Still not convinced that these are the finished production pieces. Oops, After re-reading Mac's post, I see it is described as lo-po intake.

I found the prices while I was at work at advance auto the other day. We can get them second source. Our retail pricing is as follows, but nothing is in stock yet. Ill bet pricong will change when the get them. Of course you never know.

heads 60819 $791.66 ea
intake 5409 $521.84
intake 5408 $494.89

I was suprised on the price for the heads. I thought that was a pretty good price.

Here's some more pictures. They didn't have any hipo intake or lowpo heads at the show. I mentioned that the lowpo intake might come into contact with the valve covers, like Aubrey mentioned, and they said it would be tight but would fit. Based on the lowpo intake picture, I guess it would be safe to assume the lowpo heads do not have the hole between the runners. :dunno Man, this is all getting very confusing.

The pushrod holes look round. I guess they will have guideplates?:scratch

Hey folks,
I tried to lighten up the photos to see what the bowl area looks like.
Good looking castings and no combustion chamber either.

I can hardly wait until someone runs a comparison between some stock 690's, Edelbrock, and BWR heads. I really don't see any losers, I think I'd be happy with any of them.

Larry, the Edelbrock rep told me they have the flow numbers on their new heads. He told me to call tech support for the numbers.

[Richard/SIA]

Something like 300 CFM as cast on the intake side? :clap

Cecil,
I read on the edelbrock website that the heads come with hardened guide plates.

It'd be nice to see a side by side comparison on the same flow bench, buy a impartial operator. I'm more interested in the comparison than in concrete numbers. I don't think any two flow benches measure exactly the same and i assume the figures can be "tweaked" a little one way or the other.
I don't take usually take dyno numbers as gospel truth either. :rolleyes:

[Ronnie Russell]

larry t , I feel the same way. Tweaking dyno results and flow bench readings is common in the advertising industry. Sell the parts, that is what it is all about. non-partial compairison will not happen because there is not a financial advantage for doing so. Example: Edelbrock will probably claim a 25 hp gain with their new intakes. I would guess an honest 10hp. Don't get me wrong, I hope it is a 25 hp gain, but old age has taught me to be skeptical. I hope for the best and also am extremely happy that there are new parts available. Edelbrocks prices are fair for what they are offering and I wish them good luck, but of course I prefer BWR heads.

You know.... I'm looking at that manifold picture again...
There's NO WAY that manifold is for small port heads... no way.
That "flange" that extends up at at he mating surface, where the bolt hole would normally be... is way too high. In looking at a large port intake, I would say that the pictured manifold is a large port version.
If it isn't...
Edelbrock has an expensive little mistake on their hands:doh

Yeah, as if we ALL haven't made those:stooges

I'm sure it was just mis-labelled:coffee:

[Ronnie Russell]

Aubrey, I agree. As Imentioned before, I think these are pictures of prototype intakes. A big hurry to announce new products. Soon , someone will take delivery and post some pictures. Then, and only then, will we know for sure what is for sale. You gotta hand it to them though, they did address the road-draft tube issue quite well. Provision for pcv grommet with baffle included. Time will tell.

[MRHP]

Looks like the pcv valve is right where the coil should be. :doh

[mac1]

Went back to the show today and I was told by Randy, (one of the reps), that the 7/16" rocker arm stud and exhaust manifold threaded bosses have steel helicoil inserts for added strength. Makes good sense to me.

[482STROKER]

I'm not sure about the heads but I know for sure I am going to have a set of those valve covers real soon,

[Skip FIx]

I can speak for Edelbrock's flow number on Pontiac heads(yea I know not a W) and they are right on what most guys measure, around 270 for the 87cc chambers and 280 for the 72cc head(better short turn). So I would trust their numbers as being pretty close.

Now their claims on intakes is a different story! The Pontiac Performer they claim as better than stock isn't, but the stock intakes do pretty good. Performer RPM is a GREAT intake.

I'm interested to see how their numbers are on the heads. I do like the more curved turn on the runners of the intake. Who knows maybe they will make a good Performer RPM single 4 too, but then most guys building Ws like multi carbs-myself included.

[BROOKLYNSS409]

WOW! these pics are great.

I guess everybody here is looking for a way to try these new babies out too.

what can you get for your old 690 heads? Shouldnt they be worth more than a new set of Edels??

:beerbang

Coil .... We ain't got no coil . We don't need no coils.
I don't have to show you any stinking coil!"

Hey..........................I remember that guy!

Larry, at the track is the true dyno, put aside all the BS flow numbers, over the 1/4 will tell all.

Amen to that brother!

I'll agree, MPH numbers on a time slip don't lie. But I'm getting too old to change the heads a couple of times in a day or even a weekend to check the results. Sounds like work to me!:eek: I guess if you have enough data on your combination, A/B/A testing wouldn't be necessary. It'd still be labor/$$$$$ intensive though.

[BROOKLYNSS409]

has anybody ever tested 2 engines side by side?

I remember hearing/reading that even 2 exact engines will have diff numbers/ results.

correct me if I'm wrong

meanwhile the excitement of all the new 409 parts will hopefully promote more parts and lower prices too :beerbang
