Local yard wants $2,000. for the only 5.4 they have and it has 40k miles. I understand the 8-bolt flexplates are discontinued and I would have to find a used one but yards will usually not separate thenm from the engine or tranny?

4.6 is here to stay? Aluminum block built to take the revs I guess! Good luck all!

if you have a pull-a-part local to you or a similar yard you can go in and pull your own

skylark · 05-13-2008, 05:07 AM

We have a local pick-n-pull. I have had 3 back surgeries and cannot pull spark plugs without feeling pain. Besides they don't have one! I can wait. Car is still running well, just a weak cylinder. Would like to do a motor as cash allows so when I need one it is ready to go. It is the torque of the 5.4 that intrigues me!

r3dn3ck · 05-13-2008, 01:49 PM

all you need is the flexplate from an automatic mach1 or a marauder IIRC.

Actually, no... those cars used the cast crank with 6-bolts. The 5.4 uses an 8-bolt crank IIRC. You need an 8-bolt flexplate. You should still be able to find one relatively easy.

skylark · 05-13-2008, 03:38 PM

Yeah, not sure hw easy one will be to fond as most will not separate them. Also the only 5.4 I have found is $2000. and that will not ne bought by me! 40k mles or not! I want to rebuild one and have it strong.

cdjnight · 05-13-2008, 05:12 PM

I bought one through Jegs, it was a ford motorsport part]

skylark · 05-13-2008, 05:30 PM

How about a link? I was told the plate has been discontinued but that does not mean there are not some around!

I'd rather spend 800 more on a MMR 5.4 shortblock... but that's just me...

Where are you, I have a complete one in my garage on a stand for $600? I'm on the north side of Baltimore close to PA line?

I am located near Syracuse, NY which is about 6-7 hours from you. I got my SVO intake from a little, well not little as I had never seen traffic like that, just west of D.C. That was an 8 hour drive. I need to get a flexplate before I get a motor though your price seems fair, what condition? I plan on a rebuild but would not want one with a spun rod or main bearing. I had a fellow member offer me a flexplate for the cost of shipping but he deleted the post and has not yet responded to my question as to why yet? He said he had 3 of them and I could have one for the shipping costs.
The Cobra's never had automatics and the mach 1's that did come with automatics had 6-bolt cast cranks like the GT's so it seems the vehicles that had the 5.4's with automtics are the best place to find an 8-bolt flexplate. One of the guys here sent me a PM with a couple of links but the first webtv would not access and I have yet to try the others.
Once I have a flexplate I can proceed as I have decided that a 5.4 is the way I want to go as my original intentions were to have the Stang as an interstate cruiser. With a 5.4 the 4.10's could go and the 3.27's be reinstalled. I have a great 10" Dirty dog converter with a 3300rpm stall that would have even a higher stall with the 5.4 so that would help the 3.27's get it going! The tune locks it at part throttle in 2nd gear and at WOT 1 second after the shift and that tune dropped .2 from my 1/4 mile time. I would build the 5.4 with higher compression, say 10:1 or even 11:1 for power & torque. Hitech Motorsports tunes their cars with 87 octane with 23* total timing and gets 45whp from their stage 2 cams with that tune and headers. Amazing power as that is on a stock head, intake and even TB motor. One guy got 300+WTQ frokm 3300-5000+rpm. Imagine what a 5.4 would do? Could get interesting! Want to stay NA and 5.4 sounds like the way to go. Let me know what you have in a PM or here and if you have an 8-bolt flexplate also? THX! Mark

skylark · 05-14-2008, 09:05 AM

Does anyone know the height the adapters add to the 5.4 motor? I read the 5.4 sits 1" taller and then whatever the adapters add and I would like to keep my SVO intake? I can measure the existing distance wikth the SVO so I would know that. If I had to sell the SVO I could get a good amount as it has the coolant mod done to it and it has the Bullit rails needed to adapt it to the PI heads.

caballo · 05-15-2008, 12:06 AM

KarKraft has 5.4 4V to 4.6 4V intakes adapters for $369.00!!!!

SleepingGT · 05-15-2008, 11:19 AM

99/00 mustang GT's came with an 8 bolt flexplate(my 00 gt has one)

o yea, and you can buy them at places like oreillys/advanced etc

SleepingGT · 05-15-2008, 11:29 AM

8 bolt flexplate part number for Pioneer is FRA470

Oreillys charges $61 for it

cdjnight · 05-15-2008, 02:36 PM

Having problems getting a part throttle surge out of mine, anyone got a tuning clue or any ideas??

Too much timing or too lean. If you have a tuner back the timing in the rpm range it is surging. Is it idling OK, so you know there aren't ant vacuum leaks? Likely the timing though as I have had that myself before.

Where did you see that those 2 years came with an 8-bolt flexplate? I did not think ANY Mustang came with an 8-bolt flexplate, not any year! have a link to that?

8-bolt means 8-bolt crank and even the Mach 1's with the automatics did noit have an 8-bolt crank!

JScottGT · 05-15-2008, 06:23 PM

The '99 and '00 Windsor built 4.6 engines used an 8-bolt cast crank. That is what my 4.6 had.
