New Exhaust For Center Dump Exhaust Manifolds In A 1965 F-250

[Chris430]

Got my exhaust done on the Edsel / Mercury exhaust manifolds. They fit the truck well, the exhaust man was able to jog around the starter Bendix. Also had to cut a corner off of the driver side engine mount to make way for the flange. I used the factory 63/64 352/390 Galaxie engine which allowed the FE engine perches to remain in the factory location. The mesh extensions are a little insurance for the crack prone manifolds. Nice having a quiet truck again.

I was wondering what the outlet hole size is on those center dump manifolds, eg 2.25" or 2.50", and what it was on the later rear dump manifolds you didnt use?

Hey Werby, Message sent. These manifolds were for a 58 year modelnand the exhaust outlet is 2.25 ID. A hand full of folks I found all had cracked manifolds like this. I heated the right side a dull cherry color and braised the crack between the stop holes. So far it has about 3,000 successful miles including an 8 hour trip on it. The 59 Lincoln exhaust were cracked and scrapped long ago. I'll post the 64/65 Lincoln manifolds when I get back to them. The Lincoln's were of the same rear dump design but did have different casting numbers.

EDIT: I am not a skilled welder however I have been able to get by. Out of all the manifolds I remember working on, many of them FE, I have not worked with a softer metal than that of the right side manifold. Although these weren't a date matching pair of exhaust manifolds I have found others say the driver side was the first to break.
