About 8 years ago, I put a set of headers on my 78 F150 4x4 400. The drivers side angled down hugging the block and exited on the inside of the drive shaft. The exhaust pipe then made an "S" and ran down the right side. These were very easy to install and run pipe because of the left side being inside of the drive shaft. Every header that I can currently find exits on the outside of the front drive shaft, causing the pipe to route over or under the shaft and bending at a very tight 90deg angle. THe passenger side on the old ones had a couple of inches of frame clearance, unlike others that I have tried and rub the frame. My old ones have no name or number on them and I want another set of them. I recall that they were about $100.00. I have tried Dynomax and Hedman with no luck. I even tried JC Whitney. I can't afford the Sandersons either.
Can anyone help me with what they are?

 

I just got a set of hedman 89210 headers for my 79 f250 400 4x4, and the drivers side exits on the inner side of the driveshaft, not the outside/frame side. I think that's what you're looking for. By the way, I haven't gotten around to making a y-pipe for these headers, since the crossmember is almost directly in the way. How is yours routed? Is the crossmember modified, or is the pipe just routed in a almost 90 degree angle, then up and over. Hope that part number helps, I'll appreciate any help back.

 

I got some Summit brand ones and they are what youare talking about but that was years ago.
