Hi Wade,
After I responded I googgled the manifold and found out... no. It will sell soon.
My motor is together and runs well I have the stock intake on it with an NOS plate (100 shot)which gives me enough clearance to run the Holley 4118 carb.
I was looking for "future" parts once I pull the motor out way in the future. It came out last June, cleaned all up, prepped the engine bay reinstalled, then the car went to paint... what a mistake!! I should have left them (engine and trans)out... now there is yellow overspray in the engine bay. I will take it out again to correct the overspray issue but not for a while. To answer your question I think a dual plane would be best.
I have some parts (Cal Vit mirrors, heater controls complete, rear lights complete ect) I should put up in the forum that I do not need... and I should look for some aluminum heads and intake to fresh up the motor.... What I really want no one makes a dual quad low profile intake for a 351C, I have a matched set of small cfm 4 barrel holleys that came off my old (gone) T Bucket that would be a sweet setup. Thanks for the read hope you have a happy holiday season.
