1978 351W headers?

I've been looking and I can't find any headers at all for a 1978 F-150 351W.

You're not imagining things cuz the 351W wasn't offered in the Dentsides. Is your application 2WD or 4WD and manual or auto????

For long tubes, the closest you'll get is a 2WD with a 302. 302 shorties will work and I think it's hit and miss with 3/4 length headers (longer than shorties but not long-tubes).

V10man is gaining momentum as a positive member of FTE.V10man is gaining momentum as a positive member of FTE.
I would be tempted to try a set for a 1980 truck.

Yeah. You could try 80-95 1/2 ton 2WD headers like Hedman Elites (Jeg's PN 500-89358).. there's no guarantee that they will fit though. They're 3/4 length according to the catalog's image.

The 351W has a one-inch taller deck height and is slightly wider than a 302. If you can fab, then order a set for a 302 for your year, extend the primaries, and maybe angle them to compensate for the increase in width. Your auto trans makes things a bit easier since there are no linkages to deal with.

I did a search in the 73-79 forum for "351 headers" and came up with 17 pages of hits. A quick scan of the results indicated some fellow FTE'ers went with shorties.

Wouldn't really want to go to shorties but if I have to I guess I will.

daveengelson has a good reputation on FTE.daveengelson has a good reputation on FTE.daveengelson has a good reputation on FTE.
Same issue w/ 65 did not come with a 302; understand chassis same/simular 65-78, found Hooker longtube worked. Had to lift passenger side slightly to get the header around the starter. In addition, used 4 1/2" grinder to remove small amount of metal on passenger side engine crossmember I wanted additional clearance for header flange. Seem to recall thread on simular topic, believe member mentioning the 351w will set slightly higher than the 302. Not sure about shorties. Click the image to open in full size. Just had exhaust system installed found experienced shop can install for just about any application. Anyhow, food for thought.
