351w swap headers

[a91what]

Ok I need a set of swap headers that will fit with a 4r70w transmission and not hang so low that they hit speed bumps...

We are talking fox right?

yes for a fox, I already have shorty headers for a 302 and they will likely work fine with my 351. I was thinking of running a set of longtube or midlength headers..

do you know where I could find these? I only find them for the 302 and I know mac went out of business 4 years ago. Do you remember the part number or something other then the name?

No, but

I think BBK has Fox body 351 headers.

But what you're asking for, a longtube that doesn't hit speedbumps, could be difficult. How big of a speedbump? is your car lowered? What wheels and tires are you running? Are you using standard or convertible motor mounts to clear the 351 under what hood? (how low is the engine in the chassis?)

I'm not trying to be difficult, but when swapping in the 351 there are bolt-on swap parts sure, but at some point you're going to have to fab and/or flex the parts you have to fit the larger engine in the relatively small space. There's just enough variables here to where I think you're just as likely to bolt it on and be done, versus, needing to have a skilled person mock it up and modify the parts on the car as needed. 50/50 chance IMO. Sorry if that's a pessimistic view!

Good Luck!

Headers for the 351W in my T-Bird are custom built 1-7/8" primaries into 3-1/2" collectors and are tucked up under the car as high as he could put them. The car has coil overs so its pretty low and every once in a while the exhaust drags but its mostly the 3-1/2" X-Pipe that gets it. I will tell you that having a tubular k-member helps things tremendously with long tubes.

Key words in Aero's post were "custom" and "tucked up under the car as high as (possible)" - that's what I was trying to say. For this specific ask, I think whoever does the work is going to have to bend metal to achieve the desired outcome. I doubt an off-the-shelf part does the job.

I'm from Sapulpa originally - small world!

I’m in SW Jenks so nearly Sapulpa.

The guy that built my headers used a mandrel kit and I had them jet hot coated along with the x-pipe and MAC 3” car back.

BBK longtubes generally have the better quality, and better clearance with stuff like steering shafts. They tend to have the best road clearance, but the sacrifice is they have the worse transmission clearance. Ask me how I know. Everything is a sacrifice.
