What 4.6 would you use?
I am replacing the motor in my 1997 F-150. I am sticknng with the 4.6, but I am wondering what one you guys would go for.
From what I can gather I have the "Romeo" 4.6, and was wondering what other 4.6's would give me more power. I am looking into a 2001 + 4.6 from a F-150 but what else is out there?

Getting one with PI heads will give you more power in stock form like the 01. I don't think there is a power difference b/t the Romeo and the Windsor motor though.
Can also check out the crate motors performance shops sell.

infinatenexus,
You can't really use the 32 valve engine without quite a bit of modification. If you put in a PI engine then it will have more power then the Non-PI engine you have now, probably 35-40HP and since that is to the rear wheels, it is a definite seat of the pants improvement. You just have to switch over to your ignition set-up (remove COP and use your duel coil/plug wires).
Are you sure you have a Romeo engine? Most of the 97 trucks had Windsor. Look at the VIN deciphering tool on this web site and see if you have a W or a 2 for the engine code. Believe it or not, the 2 is for the Windsor and the W is for the Romeo. The difference is the Windsor will probably have an 8 bolt crank and the Romeo a 6 bolt crank. You can change them but will have to change out the flex plate for the torque converter.
I watch ebay quite a bit and have found most of the late model 4.6 truck engines for sale there have the 6 bolt crank.
You can also contact Karkraft They usually have a good selection of crate engines.

I'll check again, but I do think its a Romeo. I have found a couple low mileage motors in South Florida, I guess I'll take a day off work and pick one up next week.
Thank you for all your help.

I thought about the aviator motor, but they are a bit out of my price range.
