John Saad’s street-driven XY Fal­con com­bines elite-level build qual­ity with a 1354hp Sonny’s moun­tain mo­tor!

JOHN Saad wanted a streetable car that had 1000hp nat­u­rally as­pi­rated. “No blow­ers, no tur­bos,” he says. And that’s ex­actly what FAT XY is. With an en­gine bay filled to the brink with a mas­sive 673ci Sonny Leonard, hemi-headed big­block Ford, this gor­geous black XY GT trib­ute ex­ceeded John’s re­quire­ments with a bona fide 1354 98-oc­tane-friendly horses. If you think 1354hp is stout, you’ll be blown away by the fact that John ac­tu­ally had the en­gine de­tuned to make that power.

Us-based Pro Stock/pro Mod gurus Sonny’s Rac­ing En­gines orig­i­nally built the Hemi­headed moun­tain mo­tor for an Aussie drag racer who was look­ing to run sixes on C16. Un­for­tu­nately, the enor­mous mill was never fit­ted to a car and sat about lan­guish­ing. John’s brother Ge­orge was aware of its ex­is­tence, and ap­proached the owner about sell­ing it. Al­though it wasn’t ac­tu­ally for sale at the time, a deal was struck.

Un­for­tu­nately, with its al­loy rods, sky-high com­pres­sion and Mount Ever­est cam, the an­gry full-race en­gine was never go­ing to be happy on the street. So it was packed into a crate and shipped back across the Pa­cific, to Sonny’s shop in Lynch­burg, Vir­ginia. They stripped and com­pletely re­built it with dif­fer­ent rods, pistons and a more streetable ver­sion of Sonny’s spe­cial 60mm camshafts.

The foun­da­tion for this ex­treme Ford is the af­ter­mar­ket cast-iron Premier block by Elim­i­na­tor Per­for­mance Prod­ucts. Based on the fac­tory 429/460ci (385-se­ries) block, it has been sig­nif­i­cantly light­ened by LSM Sys­tems Engi­neer­ing, who whit­tled around 32kg out of it. The cast­ing fea­tures spe­cial high-flow wa­ter jack­ets to help the keep mon­ster cool, along with a raised cam bore to clear the hefty Car­rillo bil­let-steel rods and whop­ping 4.843-inch Bryant bil­let crank. If you punch the crank’s stroke along with the Di­a­mond forged pistons’ 4.703-inch di­am­e­ter into an en­gine ca­pac­ity cal­cu­la­tor, you’ll get a whop­ping 673ci!

The enor­mous hemi­spher­i­cal cylin­der heads are just as ca­pa­cious. They’re Sonny’s own de­sign and have ports that look big enough to fit your fist into. The ex­otic heads are bridged by a mam­moth sheet-metal in­take man­i­fold, topped with a pair of Hol­ley’s leg­endary 1250cfm Dom­i­na­tors. De­spite be­ing nearly 60ci smaller than Sonny’s 729-cube Ex­treme Pump Gas Ford big-block, this donk is lineball power-wise thanks to ex­ten­sive CNC head work. Sonny’s Rac­ing En­gines is so happy with how it turned out, there’s a pic of FAT XY’S en­gine bay on the com­pany’s web­site.

As pho­tog­ra­pher Thoro­good has noted, the sheer scale of the en­gine is epic – which is what you need when cre­at­ing a 1000+hp, nat­u­rally as­pi­rated street mill. And it didn’t stop there. While Sonny’s sig­na­ture for­ward­fac­ing, belt-driven (off the front of the cam) dizzy stayed, the drag-spec wet-sump set-up was swapped for a Moroso four-stage dry­sump sys­tem. This en­sures vi­tal oil pres­sure is main­tained when­ever John mashes the loud pedal for in­ter­vals some­what longer than six sec­onds.

“Todd at Sonny’s was mas­sively help­ful,” John says. “It was a scary propo­si­tion to stick the big-dol­lar en­gine in a wooden to box and send if off. But Todd looked af­ter ev­ery­thing and made sure ev­ery­thing was right and it came back spot-on.”

FAT XY’S 1000hp-safe driv­e­line in­cludes an Al’s Race Glides TH400 com­plete with Reid case and bil­let in­ter­nals. Af­ter dyno­ing the en­gine, Sonny’s sent all the specs to Neal Chance, who pieced to­gether one of his bul­let­proof con­vert­ers. Con­tin­u­ing rear­wards, you’ll find a four-inch Mark Wil­liams chromem­oly tail­shaft and 40-spline Mark Wil­liams diff with a sheet-metal hous­ing by Red at Craft Diffs.

As dom­i­nant as that hemi-headed big-block is, the rest of FAT XY is sim­i­larly grand. Michael

UN­LIKE MOST PROJECTS THAT START OUT AS BAS­KET CASES, FAT XY WAS BORN FROM A VERY TIDY PHASE III TRIB­UTE, WHICH HAD BEEN BUILT WITH A NUM­BER OF GEN­UINE PARTS

“As well as all the com­pa­nies that were in­volved, my broth­ers Nick, Michael and Ge­orge along with mates Rob, TJ and Shadi pretty much built the whole car for me,” John says. “They did so much, I can­not thank them enough”
