For sale is my Pro-Street 1971 Buick Skylark that's tastefully dressed & badged as a 1970 Buick GS Stage 2. Engine: 350ci with Twin Turbo's Transmission: Built TH350 Rearend: Richmond 4.56 Two video's available on YouTube: i8VzPjolS_E and YZ13Kx5XnT4 This car runs and drives great, and is street legal. The engine is a freshly rebuilt Buick 350 with less than 100 miles on it. It has ported heads, Poston 114 cam, roller rockers, aluminum intake, blow through Holley 650 with full annular swap, aftermarket metering blocks, new baseplate with 4 corner idle, and tri-y turbo headers. It has a chrome high amp alternator, HEI distributor with vacuum advance/boost retard, an MSD CD ignition box with rev limiter, and Taylor 8mm wires. It has an Aeromotive A1000 fuel pump, Mallory boost referenced bypass regulator flowing from an RCI 16 gallon cell in the trunk. It also has the TA Performance high volume oil pump.The short block is all stock but has a big crank and a deep true y-block, making it amazingly tough. It has an aluminum radiator with an electric 2 speed fan that keeps it nice and cool. The turbos are 50mm hybrids running through a 2 in 1 out style intercooler. It has twin 35mm wastegates and dual blow off valves to protect the cold side piping when coming off boost. It has full mandrel bent 3" exhaust on each side feeding stainless perforated tube race mufflers. The turbos are very well matched and because they are hybrids there is essentially no lag between throttling up and accelerating. With the conservative 8psi tune it runs great on 93 octane pump gas, which is all I have ever used. The transmission is a strong TH350 that has alto reds, kolene steels, stage 2 shift kit, extra frictions, a 3800rpm 9" nitrous converter, and has a stand alone trans cooler with a 10" fan. The converter isn't too loose on the street, but hits really hard when you want it to. The shifter is a B&M dual lockout Pro-Stick with a .44 magnum revolver cylinder handle (it holds real rounds). The driveshaft has heavy duty universals. The rearend is a shortend 10 bolt upgraded with a Richmond 4.56 ring & pinion and zytanium locker. The back half suspension is hung from 1/8" wall 2x3" rectangular steel. It features Camaro/Nova monoleafs for excellent comfort on the street, and true & tried track performance. It has custom traction bars integrated into the spring plates. The 6 point roll bar is .135 wall 1 3/4" steel. It has Summit racing bucket seats with a driver's side RCI harness. It has a Grant woodgrain/ polished aluminum steering wheel. The aluminum dash is full of Autometer Sport Comp gauges and Innovate wideband AFR system for on the fly tuning info. The bumpers, hood, fenders and trunk lid are all VFN fiberglass. Some of the pictures have the "GSX" stickers on the rear fenders and trunk lid but I removed them and installed OEM "GS" and "Stage 2" emblem's. The core support is fabricated aluminum and drops about 25lbs off the nose. The battery is in the trunk. There isn't anything under the hood that doesn't need to be there. It easily overpowers the huge 32x17.5" Mickey Thompson ET's going 30mph. At part throttle this car is quiet and mellow. At about 1/3 throttle the turbos start to whine and stacks up a few psi in the bonnet. At around 1/2 throttle it gets really fun. But at full throttle / full boost, this car launches straight as an arrow and with an aggressively mean roar. I took it to the drag strip once and my best run was 7.73 in the 1/8 mile. Although the exterior is solid there are a few scratches and the windshield has a crack in it. The interior is okay except for the driver's side door panel is missing and the rear seat has a couple splits. This car is really clean and mean and it is being sold as is with no warranty. I am not interested in trading it for a Chevelle, GTO, 442, Camaro, Mustang, Cuda, Harley, etc. because I already have a new project I'm working on. That is the reason why I'm selling this one. I am extremely confident that the new owner will thoroughly enjoy this powerful muscle car as much as I have. Please feel free to email me if you have any questions. Thank your for your interest and good luck bidding!
