In the long run it would be better. If my tranny held up.

What kind of tranny wouldn't hold up? 4R70w ? What do you have?
Alls you have to do is lengthen a few wires - use your coil packs - forget about 5four COPS ..Look thru posts from JMC , he's posted what you have to do - he's done it . Many others have as well.

I have the M5-RD and i think somewhere i also read that you wouldn't think it would hold up to it.
But there is so many unknowns to the 5.4 swap. Like finding an exhast system for it. I would still ahve to wait for tunes to be able to run it off of the coil packs.
I have a windsor so i have the 8 bolt crank. I know this cuase i just put a brand spankin new ford tranny and centerforce in not less then 4,000 miles ago.
Heres where i stand.
Correct me if im wrong.
Spend $4k or so doing a 5.4 swap and have a truck that still ahs a ton of room for emprovment or spend $2k and had a 4.6 that is pretty much taped out as far as my money and smarts will take it.
I know with enough money anything is possible but... and i do say wit ha big BUT. Is it worth it to build up the 4.6.
Yea , ok .. Didn't know you had that trans - I thought I may have got ripped off when I purchased my 98 because I noticed after the fact in 99 that I paid a hell of allot more than most 150's on the market . I was to busy back then to check things out good . Then the motor blew in 2000, but that was a dealership error(negligence, employee discharged or quit, I didn't get those details) and they covered it. I lucked out tho and it was definitely worth it ..It's been an awesome truck to date (223,000 on the clock (new motor) 257,000 on the truck)..
