71 Olds Cutlass Supreme.... 830 HP 482 Olds with dyno sheets, fresh, only about 20 passes on complete refresh.... It is the top of the line for Olds performance with no expense spared and track proven... 72 455 block, .60 over, water passages filled, intake valley filled and reinforced with Devcon epoxy... Full main bearing girdle, 4340 moldex billet crank, reworked and improved oil system with external belt drive oil pump and oil accumulator... ATI damper/flexplate, Diamond pistons and fresh aluminum rods, 15.5 to 1 CR, .800 lift solid roller cam... Fully ported fresh Rocket Racing/Wenzler heads and intake with TD shaft rockers.... Moroso vacuum pump, Quick Fuel 1150 carb... shift at 7500 rpm.... $25,000 in the motor alone... Non SFI engine diaper, front and mid motor plates 2" Kooks custom headers, 16volt electrical system with alternator. Aeromotive fuel system with a 16 gallon fuel cell, done right, overkill, all new wiring everywhere, reliable, done right... MSD digital 7 ignition with crank trigger, CSR electric water pump, ect...

The trans is a TSI TH400 with all upgraded internals, aluminum drums hardened input shaft, grinner aluminum transbrake, done right and overkill by TSI transmission in Addison Ill, more than 3K in the trans and its perfect... The converter is a custom made 5000 stall PTC 8 inch... Its a really nice trans, includes SFI blanket and Hurst reverse pattern shifter...

Overkill Aluminum metal matrix drive shaft... Quick performance 9" rear with moser 35 spline axles, strange aluminum center with spool and 4.10 gears, back braced housing, bulletproof... All spherical bushings fully adjustable stock style suspension in the back with QA1 shocks.... Fully adjustable spring loaded wheelie bars included and needed...

QA1 drag race adjustable front struts, trz light weight control arms, Aerospace front and rear brakes with line lock... Light weight American racing wheels, custom aluminum core support, fiberglass hood, full gauges ect...

This car hasn't seen the track in a few years, needs new tires, 114-116 octane race gas, new seat belts, oil change, and maybe new valve springs from sitting but probably not... I'll include a valve spring checker... Also a medium sized fire suit and other extra's as well...

Its pretty much a turn key low nine second car, 3100 lbs with a 200 lb driver... Best ET at 600ft elevation was 9.41 at 144mph with a 1.28 60ft time, 5.95 @ 115 1/8 mile... Time slips included.... This car is a handful and a crowd pleaser, it will cross the 60ft clocks with the wheels up and 1-2 shift is done wheels up... Its all sorted out and it launches arrow straight every time... Will pass NRHA tech as is easy...

Just lost interest, its a hell of a deal for a racer... No way you could build this car for the $$$ there's gotta be $40K or likely more in it too much to remember....

Time to move on, just needs a new owner...
