After a 6+ year search I finally found a 671 supercharger intake manifold for a Pontiac V8. Now I am searching for information on it. And yes I tried the search function but the information that I found was old and sp****. When searching on Edelbrock's web site all I found was information on a Datsun manifold, I guess that Edelbrock has no information on items that are out of production. Apparently, when the manifold was made it didn't have provision for coolant p***ages or thermostat housing. My manifold has been modified with pipe threads at the coolant outlets on the heads so that hoses and a remote thermostat can be installed. Is this acceptable from a cooling standpoint? Soooo, has anyone else messed with one of these? What are other pitfalls that I haven't discovered yet? I am afraid that the drive pulleys etc. are going to get interesting. I have a '51 GMC that is the intended recipient for this engine. I discovered some time ago that there was room under the hood for a blower thus saving me the trouble of cutting a hole in the hood. Sorry, that is the best excuse that I could come up with.
I think you will find that your cooling system operates just as well as a Pontiac having the factory thermostat location. For my 350 SBC with an early Weiand blower manifold I tapped the front of the heads for 3/8 NPT and used -8 AN fittings and hose to an Offenhauser divorced thermostat housing.
Thanks for the information, that is just the sort of thing that I am looking for. The manifold is tapped for half inch NPT so that should get the job done.
The reason I was asking for a picture was that I was trying to buy one about a year ago. It was to mount a 671 blower And I couldn't remember what brand it was.
This manifold is for a 671 blower onto the early Pontiac heads and so will need to be modified to fit the later ones. Since I need to have a couple of cracks welded up (see pictures) I will do the modifications at that time. This manifold isn't in perfect shape but considering how long I have been searching for any Pontiac blower manifold I am thrilled to have it.
That is a fine looking intake you have there. Definitely worth the wait. If you ever find yourself in need of one again for the '65 and up, BDS has them in stock. I have had a few of them and they are very nice and come with the steel valley pan, t-stat housing and all the little knick-knacks.

I'm afraid that I am going to be in trouble finding all of the other pieces. It wouldn't surprise me at all if I have to fabricate some of them.
