I am looking for someone who has already been down this route. Someone with a 73-79 F100 with a 351w, what kind of headers are you using?

 

Also is it possible that I could just have some custom made and around what would something like that cost?
Also what are header flanges? they look as though they bolt straight to the head, but are cut extremely short, is this an adapter and for what type or problem would this work?

 

long tubes are out of the equation,it will have to be shorties unless things have changed since I had a 78 that i swapped a 351w in a few years back,no one makes long tubes for this truck/engine combo. I used MAC mustang shorty headers that I got off of ebay. the driver's side fit like it was made for the truck,the passenger's side had to have some tricky bends done to clear the frame,but it is possible. you might try to contact a user on here by the name loudfords,he has some pictures of the shorties on his truck.

 

Yep, I used Mustang shorties on mine. There are several users here running Summit long-tubes for a 302 that fit with minor tweaking. If I had to do it again, that's probably what I would use.

 

I made this swap before (same truck) and I bought SB shorty's from FORD SVO. 10 years later 351w blew and now I have the same shorty's on a 5.0 EFI

 

where can i find these ozblitz

 

I bought mine straight from a Ford dealer who sells a lot of Ford motorsport parts. Name of the dealer here in Houston is Tommie Vaughn

 

what kind of mustang did yall buy them for....87-93?

 

yep, 87-93.

 

Shorties will indeed be fittable, but there will be minimal power gain. Exhaust all possibilities for finding small tube, full length headers before resorting to shorties. Full length headers will give you SIGNIFICANT torque gain throughout the rev range, from idle up.

 

Call Sanderson, they can custom bend some headers to fit. They did a great job on the custom headers I needed to clear the rack & pinion and cable clutch on my Mustang.
