i havent had a chance to drop 'er in yet but i think im going to try a set of 65 289 falcon manifolds i might be able to get a hold of. atleast on the passenger side. i found them on craigs list. no pic but i looked up a set on ebay. they look tiny...
The drivers side will likely interfere with the Pitman arm's swing. The pass. side is the same casting as the one that was on mine, just might have an earlier engineering number. If I were you, I'd invest in headers before choking it with those manifolds.
the 63 fairlane 289 hi-po, mustang 289 hi-po had or have the same drivers side exhaust manifold(diff. casting numbers)... I have a magazine where this person went to great expense/trouble porting and polishing hi-po manifolds for the true sleeper look !!!!
well i think ive already got the right piece for the drivers side. its the pass that looks a little big tho...
if you can find the right side like in the center pic above you'll be set until you step up to headers...
well i should be getting a set of tubular automotive headers by the end of this month but you never know...
well that pass side pipe definatly didnt fit and the drivers side one fought me the whole way too. i just took them both off, sank the motor in and called it a day. its too hot out lol but yea, i know im going to need to pull her back up anyway, thats why the level is still bolted up haha
turns out the drivers side is definatly a maverick piece but for the sake of curosity maybe someone can ID the passengerside for me?? D5DE 9430 D8
Could be Granada, D5 would be 75, D would be Maverick Or Granada, E ?, casting numbers (engineering numbers) aren't like part numbers.
Same main number (9430) as the one I posted in a pic. It looks like it might just have some ribs added for strength at temp.
He won't find those parts. That is an experimental engine called "Tunnel Port 302". It doesn't look to me like a HiPo 289 right side manifold, but if it was, it won't fit a Maverick. Those travel too far back and run into the firewall. 9340 is Ford's code number for exhaust manifolds. Therefore, it will be in the part number for any Ford exhaust manifold, no matter what it fits. It's the numbers before the engineering code that determine year, make, model, etc... The "O" between the "5" and the "E" usually means the part is for a mid-size... Fairlane, Torino, etc... D= 1970s 5= The 5th year of the decade (1975) O= Mid-size E= The part is for an engine. Next is the part type= 9430= exhaust manifold Those are the important digits in the part number. Edit: I don't know why, but I was thinking the second digit was an "8"... I fixed that and made it a "5". The third digit sure looks like an "O", but I see it has been referred to as a "D".
Just a heads up... They say that you need to convert to early SBF engine stands and mounts for those headers to fit. These mounts fit a Maverick great, but they are getting expensive. The frame stand is iron, and the top has a single stud that slips down into the frame stand. They are more compact than our stock mounts. That is one reason headers fit better with them. The other is that they change the height of the engine in the bay. I forgot if they raise or lower, but the change relocates your tubes in relation to steering and such. Our frame stands are based on the mid-60s SBF stands. I believe that Ford would have used them on a Maverick too (they fit fine), but they made ours more compact. Probably helps some in the tight engine bay. Anyway, the iron stands were used on all unibody FoMoCos until mid-65. Edit: Nevermind, read below... The catalog says the old mounts "can be used" rather than "must be used" with the ES-9 header.
Good news. I found a Tubular catalog. Not my newest, so the prices are wrong, but the notes are good. You don't need the early stands for that one. It uses the early Stang Z-bar though... Attached is a scan. Just for giggles, I also attached the part number drawing, from the same catalog, of the early mounts. They give this info because many of their Ford headers work best with them, rather than the stamped steel ones from later cars.
