We wanted to do a online build-up of a recent race engine for one of our customers. The customers goal for the 2000 Mustang GT was 470-500 RWHP. We figured we would share the build up with the modular community and show what it takes to build an engine of this Caliber . Follow with us as we complete the final assembly on this TFS headed engine. Some areas we go into deeper than other so if you have any questions please let us know. This build is not intended to be instructional but more as just a rough outline of what goes into assembling a Modular Longblock, if you have any in depth questions feel free to call or ask us here!

The Build up is based on a N/A combination with a 5.4 forged MMR shortblock and TFS heads with compression in the 12 to 1 range (which of course can still be used on pump gas with the correct tune)



The Block begins with machining and decking to insure that the cylinders are square to the block, after the machining process the assembly begins:

The block is moved to the stand where all of the oil gallies and passages are cleaned with compressed air.



Once this is done we begin the assembly by placing the Clevite Main bearings into the block and adding Royal Purple synthetic assembly lube to the bearing surfaces.



Once the bearings are lubricated we carefully lower the balanced crankshaft into place and install the ARP main studs and caps.

We can now check for adequate thrust clearance by adding a dial indicator to the block and measure for/aft movement.

Below you can see the ARP main stud kit installed with the main caps in place.



Next the tech sets the gap on the Speed Pro file fit rings , The rings are filed for each cylinder and then installed onto the Manley Forged Pistons



The Pistons and rods are assembled next using a light coating of assembly lube.



The pistons are now ready to be installed, a good quality ring compressor such as the ARP tool is recommended to prevent chipping rings or other piston damage, a light coat of

Wd-40 is perfect to help the piston slide out of the tool and is also helpful for a fast ring seating upon initial start-up.



We repeat the last step for all 8 cylinders turning the crankshaft through after each piston is installed to verify smooth operation and correct tolerances (rod side clearance)



With all eight pistons installed and the rods torqued to spec we can now concentrate on the top end of the build




The ARP head studs, dowels and gaskets are installed next in preparation for the heads



Prior to installing the heads we give them 1 final wipe down with brake cleaner on the deck surface to remove any grease or oil that may prevent them from sealing



The Heads are installed on the new 5.4 Forged MMR shortblock and torqued to the manufacturers spec using ARP moly lube on the threads.



The picture below is a great shot of the new beefy TFS cam cap hardware, this helps eliminate unwanted flex in the valve train that can be power robbing!



Next we lubricate the cam journals and install the MMR custom N/A Camshafts and Billet cam spacers. New factory lifters and followers were used for this build-up.



Next we install the MMR Street/Race Oil pump and prepare to install the front timing components.



The gears, guides, tensioners and chains are installed and degreed per the cam card to verify opening and closing valve events. This is done using a degree wheel, a MMR solid lifter and a dial indicator.





Below we test fit the Moroso Sheetmetal valve covers. For those interested in this head/valve cover combo some clearancing is required.



Last but not least we top of the engine with a MMR port Matched Edelbrock intake and Port Matched 4.6 to 5.4 adapters.



This application will also use the MMR Adapter that allows the stock style plenums to be bolted on to the edelbrock intake.



Hope everyone enjoyed the build up, the final assembly on this build from the start to finish as shown involved over 14 hrs total labor and involved two different MMR employees. Some of the steps were not shown and we may go back in and add them if questions are asked regarding anything specific. Next is the installation and dyno test! Stay tuned!

Thanks for reading!

No, the engine is alive and well! The owner actually even posted some dyno results in the other thread linked.

They can be found in the other post linked above posted by the owner of the engine. If you can find it let us know and we can see if we can locate it for you, thank you for your interest!

I'm pretty sure this is my engine! If not I have the same components, compression and internals. And I finally have some dyno results for the boys! First let me apologize for not posting any results for…well years. But here they are, the story of my 5.4L, everyone gather around :p

When I first got it installed, I ran it with JBL shorties on 2.5inch super 44s, 30 ibs injectors, and I took your guys advice and went with the 5.4 HPS highball’r with a nice big 78mm BBK throttle body to top it off. I couldn’t be more pleased with it, fit under the stock hood and all! Had lots of balls and I slowly upgraded everything else. All the Rear suspension goodies, TKO600 W/ bombshell, upgraded cobra rear end with 3.73s, AJE k-member and A arms (high suggested to anyone doing a 5.4L swap) full MSD ignition and DIS 4 box, and much more that im to lazy to name. Then moved from norther Canada to closer to the boarder, now in Victoria,BC. Once settled in I proceeded to make myself a set of long tube headers, and let me tell you, what a bitch that was! Was the hardest puzzle iv ever had to do. But after much time and effort I have a nice custom set of headers (1 5/8 primes, 3 inch collector). Soon after went to the local dyno shop 5252 Motorsports and got this thing in tune and running as it should. After farting around with it for a afternoon, the results are in…drum roll please!....366rwph @5500rpm and 391ibs of [email protected] NOT BAD RIGHT!? Ran beautifully, a 12.09 best in the 1/4…but…
“fast enough, never is.”
Disappointed I didn’t hit 400rwhp I went back to the drawing board. After plenty research and thought, I came to the conclusion that the intake was choking off this engine for the amount of flow the heads have. So I tossed the 78mm throttle body and the HPS intake (NOW FOR SALE! Email for details), dusted off that big Victor Jr and MMR adapter plates and port matched them to DAMN NEAR perfection to the heads and strapped it on the top. In addition, I got the Edlebrock inlet elbow with a massive Accufab Race 90mm fox throttle body YEEEHA! Added a custom 4 inch tubing cold air intake to the mix, and if that wasn’t enough…. a NOS BigShot plate with 190pills with all the electronics to run it correctly without the earth shattering Kaboom (haven't used it yet). Upgraded to Ford Racing 39 ibs injectors (overkill) and put it on a nice diet, losing a good 80-90 pounds and got a set of electric exhaust cut outs, to still keep it street legal….ish hahahah. Went back to the fellas at 5252 Motorsports and we played around with it once again. After a afternoon we were pleasantly surprised by the results. We opened up those cut outs, and let that beast breath…..results are in…drum roll!.... 436rwhp @ 5900rpm with 472ibs torque @4300rpm without the nitrous. BOOOM! More torque the better! Click the facebook link to see most current photo of the beast. There you have it! Numbers you have been waiting for fellas. Again my apologize for the long wait. cheers
