I am getting ready to block my crossover on my intake. I am using a product "Hard Blok 860228-Hard Blok Engine Block Filler" along with block off plates and gaskets. I had to order more than what was needed so if some one would like to fill theirs as well let me know. I am in Magnolia Texas near Houston. I hope to do it this weekend but will wait if some else would like theirs done as well because I have not yet pulled my intake.

I mentioned to a performance engine builder that I was thinking of using HardBlok to block the crossover. He advised me that it was not suitable as the oil temps get the crossover to exceed the max temp of HardBlok. I have not checked this for myself yet. You might wish to check with HardBlok.

Steve,
Following sent to Hard Blok:
Hi,
I have a 1975 GMC Motorhome that is powered by an Oldsmobile 455 Toronado engine. It has a crossover under the carburetor that
channels exhaust gases to warm the carb.
This crossover causes vapor lock problems with the new Ethanol fuels and most owners fill it with aluminum or zinc. I would like to
try your product.
In conjunction with Hard Blok I will install stainless steel block off plates between the heads and the intake manifold to keep the
Hard Blok from being exposed to exhaust gases.
Do you think your product will work in this application?
Please advise.
Thank you,
Rob Mueller
Regards,
Rob M.

I'll be interested to hear their answer.

Thanks for all the information. Rob I will have to order one of those trays tomorrow thanks for the link. I know there was a hot rod shop out east that was using this stuff on intakes with no issues but it will be interesting to see what the company actually says. I did find this where this guy used it on his GMC to fill the crossover as well http://www.gmcmhphotos.com/photos/showphoto.php?photo=18183&cat=4537
I will document what I do and let everyone know how it turns out. If there are any more brave souls in the area that would like to try it or have a spare they want filled I still plan on trying it but may wait as I do want to order that tray that Rob posted.

Charley,
You're welcome.
Good find!
I knew I saw this somewhere but for the life of me I couldn't remember.
However, this does not appear to be the same product; note the name "Durabond" on the receipt:
http://www.gmcmhphotos.com/photos/showphoto.php?photo=18167
Here's a link to Cotronics:
http://www.cotronics.com/vo/cotr/index.htm
It appears that 950 is no longer sold, however, there is 960 which appears to be a similar product.
I have sent the same email to Cotronics that I sent to Hard Blok so we can see what both of them say.
On the receipt I noted: Contact: Mike Kilroy and a phone number.
Is Mike still a GMC owner? The receipt is dated 07/22/06 and if Mike is still owns this GMC we could find out how the Durabond
worked.
Regards,
Rob M.
