Guys - Just a heads-up about what appears to be a significant problem with the "new" Weiand 8010 intake manifold. I've written it up in Dad's Engine thread on the 80 - 86 forum, but thought I needed to alert y'all.
I say "new" Weiand intake although it is still an 8010. But, it is different than the previous ones in at least two respects. First, it doesn't have the same lettering and the firing order on the top - but it makes up for that by having some extra lettering on the bottom saying "China". More importantly it has a flange on the front that covers the outside thermostat housing bolt hole and prevents the housing from being installed. IOW, it cannot be used as is.
I bought my manifold from Tim, but it was drop-shipped to me so he didn't see it. The last ones he got in about a couple of months ago were the older style, and I apparently got the first of the "new" ones. So he's gone looking for some old stock to at least replace mine and hopefully supply others of us who want one. The bottom line is that buying a Weiand manifold from anyone but Tim may well create a problem for you as it may be the new style unit you get. Let the buyer beware.
. Well aren't you just the lucky one... scratch Weiand intakes off my wish list... thanx for the heads up...
. At least it was 'China-priced' at 70% less... right?
Nope. Basically the same price as it has always been and the same price as a made-in-the-USA Edelbrock. Apparently Weiand/Holley decided they could take the production to China, save several dollars but charge the same, and pocket the difference. My guess is that they just lost a bunch of money as there must be hundreds, if not thousands, of the 8010's that are worthless. Never been a Holley fan, but am even less so now.
Having said that, since Tim says the Weiand is a bit better than the Edelbrock, especially when using the Trick Flow heads like mine, I'll use one if he can find one of the original castings new. Otherwise I'll use the Eddy with the USA sticker on it.

. And put some America workers out of a job for their exorbitant profits...
. A little minor porting/correction on the Eddy intake may make it equal or better the previous Weiand one...
Tim's not a fan of "gasket matching", which would be huge undertaking in the case of the Eddy as the gaskets are oval and the Eddy's ports are rectangular. So, if I use it I'll probably just make sure it doesn't have any goobers in it like the Weiand does and run it.
I think the key term is "properly ported". And Tim isn't saying that proper porting job isn't good. Instead I think he's saying two things. First, most of us don't know how to properly port an intake to match a head. Second, that there was no science in establishing the gasket's shape, so why match to that?
I learned a couple of years ago that I don't know that much about porting heads. I did a lot of reading and got a lot of coaching by guys that do know what they are doing. And I was able to improve the exhaust side of a pair of small-block D8 heads to some extent. But, those heads are so bad on the exhaust side that anyone could make them better with a chisel. However, when I took them in to be flow tested the guy showed me that he could get the intake side to flow better than my fancy porting just by taking a few cuts on the valve.
So I'm leaving it to people who know what they are doing, which is why I bought Trick Flow heads. As for the intake, I'll see what Tim finds. And, I'll cleaner up sharp edges from the heads as well as the intake, but leave it at that.
. Surprised it looks so different... are the China ports smaller? They look smaller looking at the more rounded runners... although round ports prolly flow better if same cross-sectional area...
. China manifold does look like some effort was made to get the vacuum ports for power brakes angled and lower so they don't hit Holley float bowls...
I don't think the Chinese ports are smaller, just more rounded. But, they are very different intakes. W/o Tim having tested one I wouldn't want it even if it fit properly.
Lol! Yes, placing it on the engine was about all the testing that was needed.
I've thought about this and realized I got lucky. Normally I would have taken the intake out of the box and installed it. But, I use RTV on the front and rear walls so I let the RTV set up overnight and then tighten the manifold down the next day. And I wouldn't have found the problem until I started to install the thermostat housing. If that had happened, with the RTV firmly set, I'm not sure what I would have done. But I am confident that would have been the last Holley product I would have owned, meaning the Street Demon carb would have gone back.
I'm known as an Edelbrock guy. Might explain why I have this in the shop:
Agreed. We cussed and discussed this on the 80-86 forum wherein ArdWrknTrk summarized the thinking by saying "I think I'm going to have to put Holley under the same heading as Prestolite. Once iconic American brands, that are ruined by offshoring to squeeze another penny". Then he clarified it with "Demon, Weiand, NOs, Hooker, Earl's and Flowtech are all Holley." And "Accel, Mallory, MrGasket are all Prestolite."
