Technical Dual Quad Pontiac

I recently aquired this NOS Offy Dual Quad Manifold for a 1961 389 Pontiac. Problem is, the water neck is, shall we say, "unique" to this manifold. So far, I've been unable to find a part number, wondering if any Hambers can provide any information?? Cross Reference or?? Checked a few sources, so far, coming up dry! There is no part number on the manifold, and it appears tobe obsolete.

Took me 2 seconds on google.

One of these hambers is affiliated with offy parts too.

Have you tried calling Offenhauser?
Some Pontiac tri powers had a thermostat housing like you would need, try Ames Performance.

Thanks all! Ames was a bust, guess I didn't go deep enough in Offy!

 

Did you procure a water neck ?

 

I see 'em on ebay occasionally too.

 

Did so! Phethean Racing!
Offy is their thing

This Hamb thing is the bomb

 

it always amazes me how many things are answered on the H.A.M.B

This would be the exact setup. Got min from ebay too, because it was, NOS, there was no water neck. Phethean Racing fixed me up! What's the engine for??

 

I thought I remembered that setup, because I've got that same 2x4 manifold and water neck back in the dusty corner. What years Poncho does it fit?

Pre '64, 326,389

 

61-64, you may have to mess with it a little to make it work on 55-60, there are some differences.

 

Engine [60 Pontiac 389] was built for my 41 Pontiac coupe but the original 239 six banger ran so good, I never changed it out. Sold that engine to "Rusty" here on the HAMB and he dropped it in a 38 ford coupe.

 

The help and information on the HAMB never fails to amaze me.

 

Amen to tha!
