hey guys i just had an idea can i use my 429, C6 & 9" rear that has foxbody suspension mounts on it. it came out of my drag car which was a 93 lx and find a crown vic with a bad motor pull the motor, trans & rear and throw my drag car stuff in it?
With enough time and money, anything is possible. Obviously, it isn't a bolt in. The crown vic came with a 4.6L, so your 5.0/fox body motor mounts aren't going to work. I am not sure if the trans tunnel would have enough room for the larger C6, so cutting and patching may be required. And finally, I know the crown vic rear end is several inches wider than the fox body... this will require either a wider rear end or a creative wheel/tire combination to make up the difference. Those are some of the major challanges in my mind... obviously, all the usual stuff like gauges, fuel pump (assuming your 429 is carb) ect ect still apply.
An LTD might be easier, since they originally came with a 5.0.
One of the problems I see with this thread is the OP doesn't mention what Model Year Crown Vic donor he wants to use. Obviously it's a very different set of problems if the donor CV is a 1996 vs a 1982 or a 1990, or a 2005!
I have to agree with Bhuff30, the project would be easier if the donor car originally came with a OHV 5.0 instead of a modular motor.
It's not clear to me what the goals of the project are.
