ok, to clear some things up - the 4.3L V6 was a chevy, the AUTO tranny was the C4 Corvette & the AWD is the same as the Oldsmobile Bravada - single turbo & liquid intercooled. at the time the towing capacity was rated at 500lbs becuz it was still new & experimental. the Syclone & Typhoon were & always will be AWD & AUTOmatic. the Jimmy GT was only the Vortec 4.3L V6, 165hp. 1991 was the only Syclone year, but Typhoon was '92-93. the 280hp rating was published at crank, but all SyTy owners claim that number was closer to the wheels.

this truck is not related to the Buick Grand National in any sense. the GN & T-Type Regals were RWD 3.8L V6 AUTOs. only shared w/ the 20th Anniv Pontiac Trans Am. although some SyTy owners would like the Buick 3.8Lturbo becuz it was better built.

this guy i work w/ has a white 1 & has had it since '95 - he suggests finding out if the motor has been rebuilt, becuz if not it's about to. he's never heard an owner that babies a SyTy; all he has is custom exhaust+mod chip & this is his 2nd motor at 125K miles
