4.6 SOHC to 5.4 SOHC

[tjm73]

In my never ending quest for more torque done cheaply I keep coming back to the 5.4 SOHC from a 99 up truck or van. It has PI heads and with adapter plates you can use the stock intake or perhaps the new Fox Lake P51 Intake. Besides the intake question, the electronics tune and the tweeking of the H-pipe to fit the wider header point, the installation seems to be pretty straight forward.

Has anyone started making the manifold adapters that would allow the PI intake to be bolted to the wider 5.4 engine? I saw when I searche dthat Reicarhadt Racing (sp?) makes some, but they appear to be for DOHC heads.

If someone made a good 5.4 SOHC intake manifold and swap exhaust manifolds that hooked to stock H-pipes. The 5.4 SOHC swap would be hot hot hot.

A 5.4 with ported heads, bigger cams and tuning would make a killer street engine. Torque all over the place and great hp too.

I emailed Jim at Reichard Racing about the adapters for 4.6 DOHC to 5.4 DOHC and asked if they made 4.6 SOHC to 5.4 SOHC adapters. Turns out Jim is Jim Reichard.

Here's what he said....

"We have made the drawings. and are planning to make them sometime when
we get caught up a little more.

Thank you
Jim"

So, they are in the works. Now someone needs to make swap headers.

4.6 to 5.4 sohc

i have had the 5.4 sohc for alittle over a year now. i got my adapters from a individual person who had them made( i'll get his email for you) and it was a fun and challeging swap. it's not to bad, i love the push you into the seat torque, and mine is a 98 nonPI motor. i have some PI heads to go on it when i get some money. i will say one thing, invest in soild or urathene motor and trans mounts. i have torn up two sets so far and i don't get on it because it needs more tuning.... but i hope this helps, all in all it's worth it to me.
