I just posted the torque thing, but a 4.6 with more torque than a 5.0, kinda hard to belive but probably true. the 351W motor is almost a bolt in, but not really I have put one in a '85 ford ranger and tubbed it out, the RX7 swap isn't that bad and I have had to make custom mounts for the ranger so I could manage, I also had to do almost that much work to get the engine in the truck and ended up w/ 11" clearence from the front of the water pump to the radiator(sp) so Im pretty expirenced w/. swaps. Im not sure if the 351W is a bolt in swap in <fox bodys. Custom pipes are not hard to make unless its mangeral(sp) bent tubes which require a special machine, I know peoplw who build 9sec. race cars with a lot of cuztom stuff on them (headers, exhaust, and some other tubing) so getting the pipes isn't hard.

 

yeah, any competent muffler shop should hopefully be able to do that stuff cheap.
btw its mandrel.
And I thought tyhe 4.6's had more hp just less torque too.
odd, oh well

 

sorry for the spelling, I never could spell.
