5.4 with mach 1 heads swap

[dannyboy1999]

Just a regular 5.0 stock coyote with the stock fuel rails and injectors and stock throttle body which is drive by wire. Only modification is that I welded a -6an fitting to one end so I can use a adjustable fuel press regulator as the holley terminator max is a return to tank fuel system. Please note that on a 5.4 with this manifold you will have to relocate your alternator as the throttle body is in the same space as the alternator. I put it were the ac compressor is using a 3/4” aluminun bracket and all new belt routing pulleys. Im seriously considering using the MFP reverse mount relocation setup as Im getting to be an old man and really want AC

Also going for a full N/A build so what comp cams would you recommend?

i converted my 98 gt to a 4v 4.6
the sparkplug wires are set up like a Hemmi with coil packs
this is just an idea if you run into problems
should work on the 5.4 4v

Mine are wires cause i have a 02 so i dont have a distributor wires come straight from the harness so i have to switch the polarity on the spark plug connector

your car is an 02

 

[dannyboy1999]

Talking about my year haha

 

[RAU03MACH]

[RAU03MACH]

i did not have to switch the polarity mine were straight up coils

 

[RAU03MACH]
