Matt Garrett - Dallas Texas - 214-878-3823

 

1963 Corvette Grand Sport,  D&D chassis GS #48 completed around 1996, real 63 regular corvette vin/title.  Late GS #003 L88 inspired engine compartment in the works 9/2018.  Reconfiguration from prior early SBC 377 that was built for this car in 96 and shown since nationally since then.   With less that 1500 miles on the chassis, we deceided to change the car up in the most profound way.  Using the BBC "mystery motor" L88 Traco look of 66 with lots of L88 components give this near 25 year old recreation a flair of authenticity representing the real car # 003 in a "should have been:" big block Trico way around 66 racing era.  Engine has a vintage L88/ZL1 3198 winters intake, 950 vintage holley, things like correct T/R bolts, linkage,  all proper TI ignition look from a worked in MSD system, cheater factory valve covers to hide the big stuff,  all worked over to function and feed what is discreetly underneath, a short deck Merlin X aluminum 540 block and Merlin 3 350 cc square port heads.  Crane Hyd roller 10:1 street engine with 697 flywheel power, dyno built and tested prior to installation.  Full hooker supercomp custom made stainless 2 1/8 primary header/sidepipes, incorporated factory 1967 powerdome L88 aircleaner system into the Daytona GS hood better than #003 ever thought of doing right.  Engine is healed to chassis on custom made interlock engine mounting designed for the power and all race thought of applications.  Not drag race engine plates, but far from over counter solid oem type, this has vibration isolation and much stronger tie in geometry and mounting points.    All this is done with power steering on an Applleton race Steering rack linked to C4 running gear, 13' ZR1 PBR brakes, full coil over fully adjustable suspension,  complete heim link components, ZR1 Dana 44 3:45 diff, lakewood bell hosing hooked to TKO 600 Tremic, Vintage air and heat, mounted and pulled by a heavy duty custom bracket (no over counter application exists anywhere to do this) setup hand made to work with all of this on Vbelts with HIGH INTEGREITY in mind for all high RPM driving and hard idle low air flow conditions in mind having all pulley and components optimized on their rpms,  Cooled by an alloy stewart pump, oil cooled by a harrison GS recreation oil cooler, using the rare factory BBC corvette short pump 3 belt and idle pulley tensioner to make what no one may have been able to do yet on one of these very tight large framed cars....  and that is have a high power street usable big block that can race and track down just about anything all with  AC/PS/PB and a full rack all in the car, weighing in wet at under 3000.... all looking vintage old school (simi) correct with no belt vibration or component integrity loss throughout the RPM range.  This is a D&D frame, but it is also a class legal SCCA full caged frame incorporated into it when it was made originally, with a fuel cell inside the framing (not trunk)  as #48 was custom built as a race car in 96, but its never been... just a show car with all the capabilities, now being reconfigured to what is above with a usable RPM power range and power to weight ratio not seen too often.  Car rides on custom made hallibrand made magnesium 17x10' front 17x12' rear.  5 lug with knock off look for safety and power capability.   Tires are currently R compound 275/40 17 front and 345/40 17 rear, stenciled in Goodyear "bilboard" for the added authentic look but in a real world performing car that would have been the "world champ" if we could time travel it back and give Duntov this one in place of the real GS #003.    All these photos are "work in progress" on the L88 type config, est complete Dec 2018.
