    I love mine, car has very slight drivability trade offs for 8000rpm potential. Cold start blip gas, float idle 10 seconds or so. Keep about 2500rpm when long haul cruising. Blip throttle if idling 30 seconds. Otherwise it drives fine at operating temps over 100° coolant temp with oil pressure in the 50psi or lower range.

    Car makes 800-815whp from 6250-7500 on pump gas, stock ecu and 10psi with 700wtq at 4750. Makes 300wtq by 2500 (feels like a stock coyote until 2500). Over 400wtq at 3-3500 depending how much boost it’s getting. If I brake boost, it spools up 10psi at 3000-3500 and pulls real good. My 40-120 roll, I’ll brake boost for 5psi at 3500rpm. 90mph grab 3rd, let out at about 8k/125mph. Combo in sig but if it doesn’t appear, here’s a quick list.

    •9.3/1 comp
    •5.3 bb stroker
    •stage 3 gt500 head with stage 3 mmr cam
    •fr500c intake
    •62/65 t4 turbos
    •t56 stock ecu sct xcal2
    •McLeod street twin disc.

    Easy driving I can hit 20mph on a tank mostly highway driven or about 12-15 mostly city. Stop and go traffic it drinks gas though, maybe 5-10mpg in stop/go crap. I can watch the needle move in just 2-3 blocks of heavy traffic.

    Great write-up and lots of good info. Livernois is a quality shop, for sure. Nice to see their operation opened for us to see, and some of their quality workmanship highlighted.

    I do!

    Stage 3 pnp gt heads with titanium retainers and stainless valves. It revs very smoothly.

    Livernois did the 5.3 BB striker with coated diamond pistons, carillo rods and their custom crank. It’s an aluminum fr500c cammer 5.3 block and intake manifold.

    Thanks, in the future I’m gonna do junk yard f150 coyotes and boost. Put the future money in real estate, whiskey, women or guns.

    Livernois did amazing but I’m now a broke bloke haha.

    I’m half serious, I definitely will go with Livernois again though. I couldn’t be happier with their work. I love the mmr cams too. I got the fr500c direct from Multimatic on an eBay nos sale.

    Ive been very hard on this combo and all I’ve lost so far in 5000 miles is timing components. It’s mainly my broke butt not getting a stand alone Holley dominator ecu to have safety kills in.

    I’d love to see that 7.3 in some rat rod and restomod builds.

    Going forward, pulling 7.3’s from wrecked pickups will probably be the go to vs coyote f150’s

    They will def have some stuff for it.

    If there's a control pack for it, I imagine it'll get swapped into everything.

    Livernois was phenomenal to work with from A-Z and didn’t have a penny of unexpected costs throughout my entire build. Everything they delivered was quality and worth every cent. @Livernois Motorsports, thank you for the excellent machine work and assembly.

    Here’s what it put down without any attempt to load up boost before the pull. This is 91octane (premium up here) and 10psi. Very little if any correction factor. We’ve sense found more low end power, and have been spinning to 7500+. This is an old pic from about 2015/16. It’s gone on to make 1208 on 30psi and a rich/safe tune. The stock computer is holding it back everywhere.

    I would and have recommended Livernois to everyone. They are exceptional.
