To my 1%'ers. My project build..(pic heavy)

I figured I'd post this here. Not sure if anybody on this site still owns a mustang. But hope you enjoy..


Disclaimer: Long thread ahead......check gas.


Since I pretty much reached the end of the road ET wise for the stocker I put cams in it. It made 355rwhp SAE but never made it to the track due to a pass side head gasket blew. So I decided to start buying parts for the new build. I was torn between a FI B-head or something different. Something you don't see everyday. I think I will achieve my goals of being different as well as make the power I'm shooting for.

Not sure many of you know, I've never been a fan of adding weight. BUT I am a fan of going fast on motor. So I decided to go with a bigger motor. About 50 cubes bigger. So I made my mind up and decided on doing a 5.4 B-headed motor. That's where I came up with the project name. :-D

Now I know B-heads suck for n/a but I like the way the intake looks in the engine bay. IMO the best "looking" mod motor. Now I do have a theory on the b's that I'm going to test. Since they lack velocity due to the large volume I wonder if they would suck the same on a larger motor. Kinda like putting AFR 225's on a 302. That's overkill. But 225's on a 408 is perfect. I'm hoping its the same...in theory.

Lastly, I wanted to do this on a budget since all I hear is mod motors are expensive. So challenge accepted. I also figured to keep the costs down I was going to build the motor MYSELF. :idea: Not sure if it will be a good idea. Haha. But building a motor from scratch is on my bucket list anyways. Anyways....if you've read all this already I guess your still interested so thanks for reading. Here are the pics.

Here's the old gal in all her glory. Had to snap a pic before I violated her.
She made 304 with full bolt-ons
320 with a short runner
355 with cams


Bye bye Mrs. American Pie....


So she sat like that for a long time while I started building the motor. Now I don't have too many pics of the short block build because I had to be sure that I got everything right so I had to pay 100% attention to the bearing clearance, ring gaps, torque specs, crankshaft end play, etc. But below is the end result of the short block.

Specs:
9.97:1
Probe Flat tops
Manley H-beams
Forged crank
Total seal rings
ARP hardware





So now that the bottom end is done I move on to the top of the motor. I disassembled the heads and sent them over to Heads Up Cylinder Heads in Dayton, OH per the recommendation of Todd (NA SVT). Nothing crazy done to them. A simple Serdi valve job, exhaust ports opened up to 03/04 heads and decked .005" to ensure a flat surface. That's it. I didn't want to open them up due to the ports are already big.




So I put them back together...
New seals
Same Livernois springs
Stock valves (cleaned)
And my small cams (238/240 .475/.450) lol.

Now comes the fun part. The intake. I can't tell you how hard it was for me to cut my very first short runner I did for the 4.6 in half. lol. I didn't want to mess it up so I made sure I took my time. But I made it through with fairly good results...a jigsaw mind you. I made sure I didn't drink the night before and have the shakes the next morning. haha. jk.



So I went out and bought another intake off corral only to take 1 5/8" from the center of it and place it between the halves. It was hard to swallow paying 300$ to only use a piece of it. But I wanted it to look like as stock as I could.




Now that it fit....off to the welder it went.

Meanwhile back at the lab...

I added a head cooling mod since it was out of the car. I made my own kit. Cost me $75. The top hose looks a little high in the pic but don't worry. I ended up taking another inch or so off so its much lower now.



Yes I know. ****ty FMS shorty's. But remember budget. lol. Not spending the cash yet for LT's..




THEN....I lubed up the engine bay and shoved her in....



Its a tight fit for sure. But I didn't have to move the MC at all.



Got the intake welded, clean it up a little. Painted it and put the runners back in. Sorry forgot to take pics of that but I can always take the upper off to show you if need be.

Put the intake on, coil packs, power steering, fuel lines, cross over tube, etc..



This is where I'm at now. My new clutch came in but idiots gave me the wrong disk. So I'm swapping it out for the right one. So I lose a week. Oh well.

I am hoping it will make 400+ around 7100. Todd says a little lower. But after I put the intake on, man is the plenum huge. lol.

And if it doesn't make 400........ I have a back up plan :dancenana: .....



Special thanks to my three amigos. Todd (NA SVT), Matt (don't think he is on here), and Kelly (Modularspeed) for the advice, tips, and hookup on parts. I'll keep the thread updated once I get her up and running and tuned.

Thanks for reading.

You and Kris (96GTS) are about the only 1%'ers left


What cams will you be running? I can tell you exactly what your port velocity will be, but need a few pieces of additional information before I can calculate it.

Cams are comp's 106460 (238/240 .475/.450 and I think 114 LC per the specs on their site). Maybe 116 can't remember.

I'm hoping another 60lbs in torque. Would be funny if it made 350rwtq.

Wow, forgot to update this thread. Not that there is much traffic here but I had a snag when I went to fire it up. Long story short, no compression on the pass side bank, had to cut the valve stems by .015. Then it fired right up.

Here is an idle vid:

https://www.youtube.com/watch?v=64LlKmCgDjk

With about 5-10 miles on it took it to the dyno and it layed now this on motor with ****ty FMS shorties:



Kinda happy I thought it'd lay down more but I suspect about 10rwhp is being held back due to the headers. So I wanted to see what it would do so I went racing.

DA was 463ft. Car is over geared now but I think I'll get another 2 tenths out of it. It went 11.61@118.76 (1.58 60ft) in February weather.

Fast forward to mid May. After I got my long tubes on I went racing again. No retune yet but wanted to see the difference. The DA was now at 1804 feet. It went 11.65@118.95 (1.61 60ft). So I can tell that the long tubes helped. Hoping to hit 385rwhp.

I thought the extra 100lbs on the nose would hurt the weight transition. But it doesn't. Got a neat little pic from the local photography people that were there.



The blower goes on in October.

Maybe I missed this part, but why did you cut the intake up like that? Trying to go as short runner as you can?

Looks good though man!!

Since the 5.4 has a taller deck height it means the heads are farther apart than my 4.6. So I had to cut and widen it for the ports to line up. I could have only had 1 weld if I would have took 1 intake and cut it longer than the other side but it would have meant I would have had to report all 8 ports and redo the epoxy on the lower. Too much work. It was easier to just add material between the halves I already had modified.

Well since nobody posts any technical stuff on this site anymore I neglected this thread. So probably my last update...

I got my long tube headers on my b-head 5.4. Here is the graph overlay between the shorties and long's. Picked up a bit. I was shocked.



Went to the track with the new power. Worse weather. Picked up in the 60ft as it went 1.51. Best 60ft ever but it caught me off guard and I double clutched the 1-2. lol. don't ask. Anyways it ran 11.62 at the same mph. It definitely had an 11.5X pass in it. Then after that I tried to come out higher and it didn't work then the track went away and I changed too many things at once. Lesson learned. But on to better things....

So New Year's Eve day my buddy calls and says come by the shop with my truck. He had a navigator come in with a rod knock. Trashed the crank. So they convinced the owner to buy a reman longblock. He GAVE me the motor. All I needed was the heads.

So out the b-headed 5.4 went. If anyone says a 5.4 DOHC with the tranny and longtubes can't be taken out from the top here is proof. lol.


Excuse the mess. I had to move **** around the garage to have space for an engine stand, cherry picker and place for the car.

Got the heads on the car. Nothing fancy. A simple valve job, and smoothed out the short turn radius a little. Had then take only .005" off the surface to ensure it's flat. That's it.

So now the fun part. What intake. to go with. I didn't want to do a boss intake as I would have had to relocate my alt and I don't like the front facing TB. So I remember the 5.4 Pioneer Al Papito and his first 5.4 intake. So I decided to duplicate it.



the above is the 2 back runners of a navi intake lower.

Finished lower:


Final product:


I reused my b-headed widened upper. Fit like a glove.

Finished and all buttoned up. I still tell people who ask me that it's a b-headed car. haha


Took it to the dyno and made 7 pulls. Here is the final numbers:


So heading to the track in September for my last and final N/A run. Come home and pull the front clip off and put the blower on. Already have the oil pan tapped, 2 Walbro 465 pumps ready for install. Probably have to swap injectors to 80's and new lines but that's easy.

Oh and I picked up a 4R75E, a FTI 9.5" triple disk stall converter (3800 stall), and a manual valve body with transbrake for $1500. I went with a MVB because I have to shift something during the run. haha.

Thanks for reading.

Oh and here is the pick of a 1.51 I did in May. I think I might invest in an ARB.

I know all that can't really be pulled from the top....

But if you got an old fvcker like the one in the pic. Those old school beasts can stand on the fenders and pull the motor out tied to their d!cks.

I really did pull it from the top. The only hard part was getting the headers above the rad support. I had to grab the tranny tail shaft and lift it up since the motor/tranny was tilted too much.

My father in law just pulled the hoist away from the car. I wasn't going to drop the k because then the car would be immobile.

Well, as for this 1%'er, my clutch is currently fvcked up. My awesome stage 3 McCloud finally bit the dust. I'm looking to replace.

Has anyone had decent luck with LUK clutches?

Redoing the fuel system now. Should have it tuned next month.

Good luck with it.

I'm been out of the mustang scene. I'd love to build another but between my bike and my new house, I think I have enough "toys" for now.

I still have my sh1tbox..... Still messing around with a mis-fire issue. I just swapped out the coil-packs again yesterday. Still have some misfires. My plugs and plug wires all check out fine.

Anyone still have mis-fires with coil packs, not COPs?

Thanks guys. Had it tuned but ran out of fuel. A buddy of mine who owns a shop said I can put the regulator on the feed side. Well it went lean at 5900.

So I moved the regulator to the return side so hopefully it should support the motor with enough fuel.

But at 5900 it made 564/510.... at only 8psi. lol I plan to spin it to 7500. I also picked up a smaller blower pulley. Should hit around 17psi at 7500.
