www.broaderperformance.com can help with the FMX parts or whatever Ford trans you have to use. Not cheap but very good. I know there are some conversion kits for the FE into a late model Stang of which some parts might apply. I'm not up on the differences but I'd imagine the stang and bird forums would know. There is a cat named Damon Sea on www.460ford.com who's done the FE/Stang swap and now runs a stroked 385 series in it. Or did last I knew. But he might be able to share a few things with you. Worth asking anyway.
