Does anybody have any experience with Flowtech pn# F3112000? Suppose to be block huggers, all the pictures I can find on web sites show a bolt pattern thats not FE. I just want to make sure they are actually block huggers and get some opinions on quality

 

I have some long tube flowtech headers in my 65 F100 4wd. I dont remember what the part# was on them. They are the FE headers they do tuck in pretty tight to the block. When the muffler shop ran my exhaust system the collector on the drivers side had to be modified slightly to put a little more clearence between it and the front drive shaft. I purchased them from jegs or summitt. I think they had them listed as fitting a 351 in their online catalog so I called the order line and made sure they were the proper ones for an FE. I was assured that they were and that they had a misprint. I knew a 351 didnt come in the 61-66 trucks but just wanted to be sure. I believe I have a few pics of them in my project on the 65 down in the projects forum if you are interested. Good luck with it.

 

I suggest Sanderson PN FF427 headers... high quality and well-built with thick, 3/8-inch flanges.
