BBK 1-3/4" Long Tube Headers June 19, 2005, 06:22:27 PM Has anyone ever tried to put these monsters on their car? I'm trying to get them in my 87 XR7. The problem I'm having is on the passenger side. The rearmost tube will not clear the firewall. I've got Pro Topline heads which have an extra wide bolt pattern for custom headers. I am able to bolt the headers off-center with the extra holes, but they need to go back another 1/2". It really looks like I'm going to have to either club or cut the firewall to make this happen. The car is gutted for racing, so chopping something else isn't that big of a deal. However, The motor has already been in and out of the car several times and I'm getting kind of sick of pulling it. I have to drop the K-member to get the motor/tranny to clear with the super deep oilpan. I just keep thinking that I must have done something stupid somewhere. Any help or pictures would be great.

Re: BBK 1-3/4" Long Tube Headers Reply #2 – June 19, 2005, 09:05:16 PM Yeah, that's kind of the way I'm leaning. If I get really ambitious, I might just cut that corner back and weld a patch over it. Quote Selected

Re: BBK 1-3/4" Long Tube Headers Reply #4 – June 19, 2005, 10:26:59 PM Are those long tubes for the 351? If so, it looks like I might be crossing those ones of my parts list. :disappoin Quote Selected
Re: BBK 1-3/4" Long Tube Headers Reply #5 – June 20, 2005, 09:17:09 PM They're for the 5.0, but I would imagine you would have the same problem with the ones for a 351. I got out my bigass hammer and made it fit. I'm not sure if this would work with a street car. I had to crush back the firewall pretty far right by the drip port for the AC. I don't think you could do this with the heater box there. I'll take some pics tomorrow, but I think right away you should reconsider these headers for a street car. Quote Selected
Re: BBK 1-3/4" Long Tube Headers Reply #6 – June 20, 2005, 09:18:47 PM They are in my 88 XR7 and it is a 351. I only had a problem with the #8 tube hitting the steering shaft. A hammer solved that. I still have my A/C working and functional, and they don't hit the high pressure lines on the passenger side. One of the only benefits of the 351 being taller, the curved portion of the header is higher than everything else. Quote Selected

Re: BBK 1-3/4" Long Tube Headers Reply #8 – June 21, 2005, 09:21:26 AM Yesterday, right after I got the engine back in with the headers on, I put on a manual rack and shaft. It's just a generic nameless unit from Ebay, but it looks just like the Flaming River stuff. The shaft is at least 5/8" away from the header all the way through a revolution. I didn't actually measure the new shaft compared to the old one, but it is definetely much small in diameter. I'll measure them and let you know. Quote Selected
Re: BBK 1-3/4" Long Tube Headers Reply #9 – June 21, 2005, 01:11:51 PM The top U-joint on the new shaft is exactly the same size as the factory one - 1 11/16". However, with a second U-joint at the bottom, the better angle may give more clearance. In my case, The shaft is closest to the header at the top joint, so changing the angles wouldn't really make much difference. Here's a few pics. Quote Selected
