Most folks don’t consider Buick’s as serious performance cars. As a rule, they are usually considered sedate luxury cars. However, for every rule, there’s an exception. Such is the case with this 1970 Skylark Pro Street GS Clone - nick named the “Street Beast” – in triple black., , It is powered by a 548 Chevy big block crate engine; built utilizing a 502 Bowtie Block, Eagle crank and H beam rods, JE pistons, Brodix BB+2 heads, Titanium intake valves, Jesel rockers, Crower solid lifters, Isky cam, Crane 2 piece timing cover, and MDS ignition crank trigger. This is kept cool by a Be Cool radiator, Flex-a-light fans, and a Wiend electric water pump. A Holley Dominator 1050 carburetor and all Aero-motive fuel system feed it from a sumped fuel tank. The 3.5 “ exhaust system is fed from a set of headers. This has one of the cleanest detailed engine compartments out there, with virtually no wires exposed. Combined, there is over $20,000 in motor alone., , The remainder of the powertrain consists of a Turbo HydraMaitc 400 automatic transmission with 3500 stall converter. Up and down shifting is automatic but you must manually shift it at approximately 8,000 rpm. It has an adjustable shift light to monitor it. There is also a Moser 12-bolt rear end with 4:11 gears., , The Wilwood braking system incorporates a front disk brake conversion and line lock - which needs hooked up. An anti roll bar is incorporated onto the rear end. Front tires are Cragers with MT 28.0/10.5x15 drag racing slicks with weld racing rims on back. Serious performance equipment inside includes a Hurst shifter and bucket seats with RJS racing 5 point seat belts., , It is a very clean car with added factory hood scoop. It has impressive paint and chrome on a straight body with a great undercarriage. It also retains the original owner’s manual., , It runs on Cam 2 - 110 octane racing fuel. It is also a documented 10-second quarter mile beast. This car was built right and is a true race car that is fun to drive on the strip or street. Sedate luxury car? Not the Street Beast!
