There are far, FAR better V8's than the gutless, spark plug spitting, PITA to work on Triton. That's my opinion anyhow.
x2...good luck fitting that wide load between the spring towers.Better measure that beast. It is really wide across the top. My guess is a lot is going to be moved. And the trans/tcase package is something to think about. You have a pretty short rear shaft to work with.
4.6 will run foreverThe plug issues were more related to the 3v engines (and it seems the 5.4 was more prone to it). The 2v’s were pretty solid, reliable engines.
They were gutless as hell though, but man they may be one of the best sounding engines ever made.
And while it is always a possibility, I’ve never had an issue with it. And I’ve had five f150’s and four mustangs. Granted, of those only three were the 4.6 and only one was a 5.4. Only “plug” issue I’ve ever had was just trying to ACCESS the rear plugs cuz the engine is set so far back.
