Offy spreadbore

[bronco italiano]

Just received this NOS Offenhauser spreadbore manifold for 302. I am fortunate to be back in-line for a Q-jet for my buddies bronco. This addition will make the update just simpler than using adapters and the other stuff. I had even called Offenhauser and they haven't made this manifold in over 30 years. Got lucky.

How much are those worth these days? I have an Offy 360 that I took off and have heard that they were decent for mileage and drivability. I'll need to check if it's a spread bore though..

Good for you. before you mount the manifold take the Quadrajet Gasket and put it on top and check that the manifold clears the big side butterflys because if you need to clearance it with a rotary file you don't want the intake on the truck. why do the work twice. make sure the linkages clear the top of the manifold too.

Great info. Thank you. I can only see myself mounting it and then uh oh!!
Will be my first Q-jet install
PDQ, I have no idea on the value or desirability. I purchased it for the simplicity of the install and one less gasket to leak.

I know the prices have gone into the 600s for the 351 model. Also it looks like the q-jet is a direct bolt on for yours. Onthe 351w offys if done they needed to be ported out for the q-jet butterflies to operate.
