I just added headers to my 75 f100 and the manifolds are in good shape, which by that I mean no cracks. The casting numbers are D2TE9431AA and D2TE9430AA. I took a sanding block to em to clean em up a bit and they look half decent. What would you guys say they go for? Should i paint em up and throw em on a ebay auction? Or are they worth just keeping?

 

a used set of stock FE truck manifolds in very good condition only bring around $75 on ebay.

 

They are to the right buyer. Finding that buyer is a problem. I sold one set for $150 ten years ago. But all others since ? Nada. They went in the scrap bin.

 

You made a generic statement on your posting. A set of FE CJ or 427 cast iron headers, factory, are going for a grand or better to the right buyers. Timing is everything.

 

true, but he said "75 F100 manifolds". the 75 F100 did not come with a 427 or 428 CJ, and the cast headers look like headers, not manifolds.

 

stock "logs" in perfect shape worth little $ to the right person , I scrapped mine not worth time to try and sell

 

If someone has a small boat they could double as an anchor.....

 

Certain passenger car manifolds are worth more because they are both necessary to fit around steering components or other parts, or because they have the correct numbers for show cars.

F-series? Not really. eBay them, as Buy It Now with a Best offer. You never know what someone will do. I had my stock V10 manifolds up at buy-it-now for $400 with best offer, and someone (a mechanic I think) bought them outright for $400. Just make sure you weigh them and check shipping costs before putting them up.
