Potential swap headers, might help someone... Hi All,
After a few months of sweating out headers for my Maverick swap, I finally took the plunge and bought a set of GM flanges (#12480130) and BBK-1569 headers. Flanges were $19 each from Hendrick Chevrolet, and the headers were $349 from Jeg's. The headers are for a 351W swap into a fox-body Mustang. Buying a set of engine swap headers from "pictures" is a hit or miss proposition, and I got really lucky on this one. If you have a tight engine compartment with R&P steering, these might work for you. BTW, the distance between the frame rails is 26" and there is about 3/4" per side on the headers.

nice. i know i've seen people mention they went this route when doing an LSx in a fox body, you make it look plain simple! not to mention cheap! I just can't justify spending $600-$700 on a set of KooKs swap headers!
I'm thinking of cutting up my SB hooker super comps, since the most I can probably get is $100 for them. I just can't see them being as high as they are!
Well since you were awesome enough to post on my thread ill post on this one to bring it back to life!
Did you simply cut the flange from the headers on the back side of the flange and follow it across? Also what size pipe is that?
thanks again for pointing me in the right direction happy Thanksgiving!

IIRC, other have already done it. The BBC header tube should match up well.

The BBC's might work, but it won't be easy. They are on 4.84" bore centers as opposed to 4.4" for the LS motors. The tubes will need to be heated and warped into position.
