Love what you're doing with the car! Dont let these guys give you such a hard time on the motor choice. I was very close to going that direction as well, prior to deciding on the coyote. My decision was based alot on price as it was significantly cheaper per HP than the brand new with warranty LS offerings I could find here in Canada. Its a 420 lb motor so im guessing that the weight is very similar to the LS.
As far as width goes, its a hair over 29" wide at the valve covers, the 4.6 is a hair under 29". No comparison in the motor though. My setup dyno'd at 510 hp at around 7400 rpm. The 4.6's need forced induction to get to those numbers and reliability and simplicity goes out the window then.
Anyway, enought about that, I'm looking forward to seeing this thing come to life.
Oh ya, changing a cam is drastically simpler and cheaper (~1/4 the price) for you. Its all about which trade offs you feel best about.
Cheers,
Wes

Thanks for the support. If the price would have been right for any of the ford stuff when I bought the LS I would have definitely gone that direction, but The price, size, power and weight of what I got (LS3 stroked to 418 w/ forged internals) was impossible to beat.
I had to fabricate my own mounts for the LS, but I have mounts for the late model ford engines that came with my K-member, so if I ever find myself unhappy with the LS It shouldn't be hard to put a ford in there.....other than comming up with the money for one.Zach
