302 in SA headers

Can anyone give me part numbers and brands for 302 headers in an SA. I have a set of BBKs out of a 91 mustang but there is no way they are going to work without completely rerouting the #6 tube.

You should take a look through my build, I used some Mac shorty's. I had trouble with the BBKs, too. The MACs are pretty similar shaped to the stock Foxbody shape, but bent much smoother.

Do you have a part # or app for the MACs?

Pretty sure these are the ones I got. I did have to massage a couole of tubes to clear the steering gear. And then clearance the firewall a little bit. Itís all documented on my thread.

The App is for a 1993 Mustang - CARB legal.

Thanks. I ordered a set of the MACs you used and hopefully they will need minimum work to fit. Once again thanks for the help.

Turns out they fit well. real minor dent in the tube next to the steering box and a little denting of the floor on both sides where the header flange connects to the down pipe. Thanks

Iím glad that they worked out for you. I wish there was a better airgap between them and the steering box - but it is what it is. Hopefully we donít burn up the steering box.
