BBK / Factory Header question June 28, 2008, 09:10:01 PM Im thinking about buying a set of bbk 1515 shorty headers for my 84 t bird. Has anyone had any experiences with these either good or bad?How many horsepower will the 1990 factory stang shorty headers support before an upgrade is nessesary? Any opinions? Quote Selected
BBK / Factory Header question Reply #1 – June 28, 2008, 09:43:37 PM I've got a set of bbk shorties and they fit really well, no leaks etc etc, if I had to do it all over again I think I would have gone with the equal length shorties. I know that you'll see a few horsepower improvement with them over a set of factory headers. So if you got the money splurge and get the bbks they will eventually pay for themselves. Quote Selected

Any opinions?Not even what a stock HO is capable of developing... In a MM&FF head shootout, a totally stock HO produced 245Hp with dyno headers and exaust system... I've had the 1515s since '99 and have had no issues with them... Running them on a Trick Flow headed 5.0... Quote Selected
BBK / Factory Header question Reply #3 – June 28, 2008, 09:59:20 PM Do your bbk,s have lots of clearance around the steering shaft? Do you think you would have enough room to put the equal lenght ones in? Got any pictures of the headers installed? Quote Selected
BBK / Factory Header question Reply #4 – June 28, 2008, 11:28:35 PM Steering shaft clearance is more than adequate w/ the shorties, I would take a picture, buy my motor isn't in the car right now so if someone else has pics of their engine bay? I'm also pretty sure the equal length shorties would clear fine, but obviously you want to be sure of that before you go and order a pair.also on a side note are you planning on putting in a new H-pipe? Because I'm not sure if your stock one will mount up with the new headers. I think they're angled a little different than the cast iron manifolds. Can someone confirm this?Another thing to consider is your shifter linkage, I went to a floor shifter to avoid the headache of messing with it you might want to ask around to see what will need to be done if you want/need to keep it column shift.

BBK / Factory Header question Reply #6 – June 28, 2008, 11:52:35 PM With new stock motor mounts, my 1515s did slightly rub the steering shaft(mainly on fairly hard right turns)... Now that they've settled, I don't notice any rubbing at all... As far as equal length, I dunno, ain't messin' with those bundle of snakes... Quote Selected
BBK / Factory Header question Reply #7 – June 29, 2008, 07:47:11 AM I bought and tried a set of hedman shorties on the 84, nothing but problems. Hit on the steering shaft,close but not hitting the shift linkage. The passengers side is the real problem. There too long and the collector not angled right.There to tight to the fire wall. The floor was so hot it would burn your hand.I took pics but i cant get them too post on this site. i tried talking to hedman to see if their jigs were out of line or maybe the wrong header got sent.they wernt interested in talking to me. The hedman is junk. I bought them a while ago and summit will not take them back either.......oh well im stuck with them.I not interested in equal length,but think i will try the bbk 1515 or ford motor sport m-9430-p50.what do you think.Still like to see pics?

BBK / Factory Header question Reply #9 – June 29, 2008, 03:13:50 PM I had a h pipe made at a local shop. It ends just ahead of the transmision pan. So what ever i get for headers i will just have to get the shop to make new pipes from the header to the h pipe.I just need headers that will fit and cause no problems.Thx for any and all info.
