Hey guys! I am new to the boards but not the mustang community.. I have spent the better part of a week reading through all of this post's 92 pages and let me say I am now more than intrigued. I want to start on the swap ASAP in order to get rid of an old tired 130k+ miles 4.6L! My first question, and possibly one of my few, most having been already answered from my readings
would be where to look for a block or complete 3 valve engine relatively inexpensively besides the obvious forum classifieds and ebay?

I found my block listed there and got in touch with the shop that listed it. The rest is history. Oh - and welcome!

I'd use a 20ga. shotgun bore brush (phosphor-bronze) and a 18" rifle cleaning rod to get down in the cooling jackets. Use a little bit of CLR in a squirt bottle and let it soak for a few minutes. It works at the molecule level so it won't eat a hole in there unless you let it sit for a very long time.
Rinse liberally with water and repeat till happy. Once you're done make sure you rinse it very well. You don't want that stuff to sit in there for days on end. |

I forgot you can try GreenLeaf or Greenway I forget what its called. Parts direct from Ford parts sources, but expencive for what you get. Google them and you will find the site.

Hey R3d - what do you think of this for those pesky water jackets ?
http://www.walmart.com/catalog/produ...uct_id=4939699 Or is that a little overkill ?

For a full motor I'd say $400, go in low and see what he says. You might get lucky or you might have to come up into the $500 range. My shortblock was $300ish i think, similar miles but it needed a rebuild.

Thanks man.. Sounds good! He is parting out an explorer so I am going to try and get the complete engine off of him and I will be doing a rebuild as well

I've never seen a 5.4 in an explorer, only the F150 and expedition.

The only adapters I have seen are to put the entire 2v intake (be it PI, bullitt, or otherwise) on a 5.4 but they aren't the greatest for flow. I believe HPS just came out with their own version that are much better.

I somehow managed to strip the threads on one of my chain tensioner bolt holes. What would be the best way to repair the threads since it's aluminum?

Helicoil or rethread it larger using a larger bolt to fasten the tensioner.

Re-threading it larger did the trick, Thanks. Patriot stage 2's and comp xe270's are now installed. Tomorrow night the beast gets dropped back in the car. I have an appointment Saturday for a tune so hopefully I'll have some new numbers to share.

I'm gonna order up that kit probably next week some time.
I just picked up a few big projects that I need to wrap up before I spent a bunch of time on the motor but things are going good so far !

Well guys new numbers are in but i'm not real impressed. 290rwhp 340rwtq on a mustang dyno. I can't believe it didn't crack the 300 mark for hp. It definately pulls hard all the way up to 6k but still. I only gained about 30 horse .

Well I can offer some happy thoughts. You've nailed at least 340bhp and over 400btq out of 334 cubic inches. That's impressive by any standard. Now... without seeing your dyno graph I can't be too helpful but I'll bet dollars to donuts there's some intake restriction happening there. With 270's and patriot stage 2's you should be seeing a little more than that which leads me to the intake thought. Also.. did you install your cams straight up or advance or retard them at all? My simulator shows significant gains by retarding them 4 degrees (which kinda makes sense as it defeats the 4deg of advance that's ground into them out of the box to avoid PTV on 4.6's).
Post up a copy of your graph and I'll see what I can tell you. Also, if you have any data points logged from the run that'd be cool to. Do you know how much timing they have you running? Oh yeah.. don't forget. you've got enough power just in tq (forget hp numbers for now) to really shock the hell out of a lot of ls1 and cobra pilots. You're well into Mach1 hp territory and the tq is going to magnify your hp numbers capabilities. Remember... hp is for show, tq is for go. Yes that's a drastic oversimplification but it works. I expect to see some 1/4mile numbers soon. ![]() You can take the RX7 as an example. Plenty of hp, zero tq. Yes they're reasonably fast if they start from a roll but from a dead stop... you'll tear em up. I'll take tq anyday. You know a big rig tractor without a trailer can run 12's with only 400hp but with as much as 1400lbs or more of tq. From a cab that weighs in at like 12K lbs... that's not bad.

hey guys:
I just created a sticky in the dyno forum. Please see the thread and update with your info. If we can all keep it nice and free of babble then I think we'll have the authoritative source for 5.4 swap info on the web. Also, if you guys know peeps from other boards with any manner of 5.4L powered mustang, please harass them to check in over here and post their numbers in they dyno sitcky in the dyno forum. I'll be policing the new dyno thread and making sure it stays a reference thread instead of a chat thread. We can chat in this one... Thanks for all of your help guys. |
