L88 427 '68 Corvette POV Drive - A Slight Rip!

Got up with an urge to drive the L88 427. Went to the gas station, poured in half a tank of 93 octane and that's where the video starts. I warm the car up briefly in the first minute and a half or so. Then I proceed to take the car on some back roads. She's a project. More videos to come. 0:00 Start up 0:55 Warm up drive 1:34 "Now she's warmed up" The L88 was a fire-breathing variant of GM’s 427 cubic-inch big-block lineup, which served as nothing short of a production race engine. Zora Arkus-Duntov led the engine project and he felt that the Corvette’s popularity would only be sustained by staking on-track dominance. Duntov seemed unwilling to let go of this notion for most of his career. The 427 cubic-inch L88 utilized the same engine block like all other big-blocks within its series. Inside this block, resided a forged steel, four bolt main cross-drilled crankshaft. Attached to this crank, were forged shop-peened connecting rods, which were secured with 7/16” bolts. Aluminum pistons were secured at the opposing end of each connecting rod, with floating piston pins. This floating pin design was used to minimize friction, and increase serviceability. The L88 featured a bore diameter of 4.25”, and a stroke of 3.76”, which was identical to that of GM’s already existing L36 and L72 427 cubic-inch offerings. However, the L88 featured a much higher compression ratio of 12.5:1. The L88 also featured an extremely aggressive solid lifter camshaft. My cam has been swapped for a more modern roller camshaft custom ground by Lunati. .695" lift 310°/310° 106 LSA Aluminum cylinder heads, which feature sizable valves (2.19” intake, 1.84” exhaust). To facilitate valve actuation, stamped steel rocker arms were fitted within the L88’s heads. These rockers were driven by robust 7/16” push-rods. The use of a third dampener spring was also employed to control the engine’s valves at engine speeds above 7,000 RPM. Fuel was supplied via a Holley 850-cfm carburetor, which is the largest Holley carb ever fitted to a production GM engine. The L88 was designed to run exclusively on high-octane fuel. My car runs on a mix of 100 low lead AV fuel and 93 octane. The L88 was officially rated at 430 HP, though this value was purposely misrepresented. They made closer to 560 HP. During the era, L88-equipped Corvettes obtained significant on-track success, tallying up numerous wins. Some of the most notable achievements include numerous first-in-class showings at both Daytona and Sebring. #L88 #427 #c3 #corvette #bigblockchevy
