🔥 Check out this beast under the hood! The 1991 Chevrolet Corvette ZR-1 
This is the legendary “King of the Hill” C4 Corvette ZR-1 — one of the most advanced American performance cars of its era.
Engine Spotlight (Modified LT5):
• Factory Spec: 5.7L (350 ci) all-aluminum DOHC 32-valve V8, co-developed by Lotus and built by Mercury Marine. Rated at 375 hp @ 6,000 rpm and 370 lb-ft @ 4,800 rpm. 
• This Build: Upgraded with the Haibeck 350 510 HP package — full porting, headers, Fidanza flywheel, and more for serious power while keeping that smooth idle and drivability. 
Paired with a ZF 6-speed manual, this thing was (and still is) a rocket: 0-60 in under 5 seconds, quarter-mile in the low 13s, and a top speed over 170 mph — all while looking like a sleek, everyday Corvette. 
Only around 2,044 ZR-1 coupes were built in 1991, making them rare collector gems today. The advanced 32-valve LT5 was revolutionary for GM at the time — dual overhead cams, four valves per cylinder, and that signature Corvette growl. 
Whether you’re a Corvette fan, muscle car enthusiast, or just love engineering p**n — this engine bay is pure art.
