5.4L DOHC Conversion Questions (need feedback)

go with the 5.4 3v. much less cost. only a little bigger than 2v and you get the hp of terminator wth a little work. still a hundred things to make, but i can steer you to less hp easier ways to get it in.

my next mods are to install the short runner intake. i have already made a number of upper intakes. not really satisfied with them, but i am settling on an idea. it points toward the firewall. then stepped headers. gonna see how much it can make up to 5500.

as far as na 4.6 4v. continental motors are a dime a dozen. they are the same internally as mach1 autos. no forged stuff, but who cares below 6500.

Karkraft has been the only site i've been able to track down some 4.6L 4v engines from. Every other site like SHM, etc is usually crate motors and custom stuff...
