Nov 26, 2020 · Things improved in 1985 when the venerable small-block Chevrolet 350 got a bump to 230 hp with the fitment of the more advanced multi-point Tuned Port Fuel-injection system. This L98 350 would later see further power boosts to 240 hp, 245 hp and finally to 250 hp with further refinement.

From 1954 to 1974, the small-block engine was known as the "Turbo-Fire" or "High Torque" V8. However, it was the 350 cu in (5.7 L) series that became the best-known Chevrolet small-block.

Dec 23, 2020 · One power plant that instantly elevated itself above its corporate title is the LT5 found exclusively in the King of fourth-generation Corvettes.

Oct 13, 2022 · The LT5 is one of the best Chevy 350 engines ever built. It is highly modifiable, and was engineered in combination with Lotus. It was one of the few engines that Chevy did not build themselves, as specialty builder Mercury Marine manufactured them.

Sep 9, 2024 · What made the ZR-1 exceptional was its LT5 engine, a double overhead cam (DOHC) V8 with four valves per cylinder, developed by GM in collaboration with Lotus Engineering.

Jun 15, 2018 · Engineers were warming up their torque wrenches for the third-generation DOHC LT5 engine when Chevrolet pulled the plug. The original LT5, of course, was a technological marvel of its day.

The LT5 motor, which had very little in common with the previous LT, was a next generation small block Chevrolet engine used only in Corvettes. It had a new block cylinder head, intake manifold, timing cover, water pump, and “opti-spark” distributor.

Jun 30, 2017 · With evidence mounting that a long-rumored mid-engine Corvette is destined for production within the next few years, we're taking a look at its speculated power plant, the LT5, and its history in GM's sports car.

The LT5 was a special engine indeed. It was an all-aluminum 349 in³ (5.7 L) small-block V8, but was entirely different from any of the other Chevrolet 350 engines. The bore and stroke were both different at 3.9 by 3.66 in (99 by 93 mm) instead of the usual 4 by 3.48 in (102 by 88 mm) and it featured a Lotus-designed 32-valve DOHC head.

The LT5 is an overhead valve (OHV) eight-cylinder, supercharged gasoline engine from General Motors. It is currently used exclusively in the Chevrolet C7 Corvette ZR1.
