Alright pretty new to swapping out to a different engine so it's not as simple as the plug and play of a replacement.

1998 F150 XLT 4X4
4.6L Windsor engine
M5OD-R2 tranny

I want to upgrade to a 3V engine for future upgrades (turbos and such)

Any recommendation for simplicity?
I have no idea on what would be most compatible as far as ECU and harness changes

 

First of all, the M5OD-R2 can't handle more power than a 4.6 PI 2 valve engine. That's not much of an improvement over what you have now. A swap to a 5.4 2 valve is relatively straightforward, our Articles forum has a thread with the details. Note that JMC did that swap and put a supercharger on it, and he's now on I think his 7th transmission.

Trust me, you don't want a 3 valve. The variable cam timing system can be a real headache.

 

Glc,
Thank you! You think just doing a reman engine with honed out valves or leave it as is?

 

Is your engine shot or are you just looking to get more power?

 

I'm at 200k and figured I'd do a rebuild. Then it escalated. So yeah, more power.
