650hp LT4, 6 speed Magnum trans, SS Chevelle Classic vibes, Modern performance. This GM Performance 650hp LT4 powered 1970 Chevy Chevelle was Muscle Car Of The Year. Its original 454ci big block replaced with reliable smooth modern horsepower! One key to success with an automotive build is to start with good raw material, and this Chevelle was a stunning example when the owner brought it to us. Once the Chevelle was in the hands of Our crew completely disassembled the drivetrain, suspension, interior, and wiring. The paint and body were in excellent condition. With all components removed, fabrication began with fitting the massive Tremec Magnum F series manual transmission into the Chevelle’s transmission tunnel. No easy task, but well worth the effort. With the LT4/T56 combination fitted, a full compliment of suspension upgrades from Umi Performance were added, including double adjustable Viking shocks, fully boxed, braced, and stiffened numbers matching chassis were bolted to the body after a quick clean up under the car. This horsepower level requires the ability to slow everything down fast, that’s why a set of Pro+ 6 piston caliper, 14 inch rotor stopping gear were used from Baer Brakes. With everything installed we could move to exhaust, Ultimate headers was first on the list to find a set of high quality header for the LT4. They sent a perfect pair of headers for fitment and we went to work modifying the mandrel bent stainless steel parts from Stainless Brothers to complete an exhaust worthy of an art show installation. Completing the drivetrain, we used a Holley Performance wet sump mid mount accessory drive along with a wiring harness and flashed E92 factory pcm, and GM fuel pump module from Speartech. The interior of this Chevelle features a rare factory optioned saddle color, including bucket seats and center console. Instrumentation from Dakota Digital fill in the factory SS dash with modern technology and classic vibes. Fast ratio power steering, full custom Bluetooth audio, and air conditioning that’s upgraded with a Sure-fit Vintage Air system and smooth firewall.
