The objective was reduced emissions and greater amounts of power. II LT1 took TPI to the next level with features that made it a vastly improved small block. Port fuel injection coupled with aggressive roller tappet technology made the TPI a quantum leap in performance. It offered incredible performance coupled with something unheard of with high-performance V8 engines of the era-fuel economy. TPI set a new benchmark for performance when it debuted in the all-new 1984 Corvette and the white-hot 1985 IROC-Z Camaro. Chevrolet V-8 small-block, which was a cut above the Tuned Port Injection small-block first introduced in 1984. II) fuel-injected small-block in 1992, it was a more-advanced 350 c.i.d. When Chevrolet introduced the 300-hp LT1 (Gen. This block has been line-honed, bored and honed, and the decks cut to give us a clean, crisp, ready to assemble short-block. The block has been professionally cleaned, prepped and machined for this build effort.

L&R Engines of Los Angeles, CA provided us with a standard bore LT1 5.7L block bored and honed. Intake manifolds, as one example, are not. Some items are interchangeable-some are not. The LT1 block really is an entirely different block and needs to be treated as such. Instead, it has an oil pump drive stuffed in the block in back secured by a single bolt.

It doesn’t have an accommodation for a distributor like most Chevy small blocks. What makes the 1992-97 LT1 block different from the traditional Chevy small-block is what it has-and what it doesn’t have. What we’re about to do here applies to both the 350 and the 265.

There’s only one other LT1 block casting numbered #10168588 for the smaller bore (3.736-inches) L99 4.3L V8 (265 c.i.d.), which was available in the Caprice as the base V8. This block casting was used from 1992-97. We’re working with a 1996 vintage LT1 block, identifiable by its “327” visible in the block and a casting number of #10125327 for the 5.7L V8 with a 4.000-inch bore. What’s more, there was so much you could do with it in terms of performance. In performance vehicles like the Impala SS, Camaro, and Firebird, it roared out of traffic lights in an inspiring fashion.

What made the LT1 series so successful was greater amounts of power by yielding a broader torque curve enabling full-sized luxury cars to accelerate aggressively to speed onto the freeway. The LT1 engine in displacements of 265 and 350 cubic inches was employed in a number of General Motors vehicles including the 1992-’96 Corvette, 1993-’97 Camaro and Firebird, 1994-’96 Chevy Caprice and Impala, Buick Roadmaster, and the beasty Cadillac Fleetwood luxury rides. There are plenty of OptiSpark ignition choices to meet your ignition needs. Inside the LTCC package, you have the LTCC module and the harness with eight leads, each with a Weatherpack connector and ground wire, a pigtail connector, and four non-harnessed wires. The LT1 coil-on-plug converters with adjustable retard and intelligent rev limiter still use the optical module in the OptiSpark distributor, but without high-voltage passing through it. The Lingenfelter Performance Engineering coil-on-plug conversion solves the OptiSpark ignition issues. You can even retrofit the LT1/LT4 with a cool LS coil-on-plug ignition system and eliminate OptiSpark entirely. MSD, as one example, offers a terrific OptiSpark replacement distributor as does Accel. It has also been refined and improved by both GM and the aftermarket. However, OptiSpark has always been problematic. The cam-driven water pump with reverse-flow cooling and OptiSpark ignition system were revolutionary. II LT1 Chevrolet small-block (L98) introduced in the 1992 Corvette was an updated version of the time-proven small-block first introduced in 1955 with its share of interesting refinements-some quite controversial. TPI endured and remained an industry standard for years. Tuned Port Injection (TPI), which was tunable and certainly a smashing success. Injection in 1982, which didn’t impress anyone. With and Chevrolet was paying close attention. Those fuel-injected 5.0L Mustangs were a force to be reckoned Performance became more in style, with Chevrolet leading the pack in that age-oldīattle with Ford. By the mid-1970s, the honeymoon was over. In the years to follow, the LT1 lost adrenaline to tough federal emission standards and higher auto insurance rates. It was the last really hot Chevy small-block ever done, with the exception being the high-revving Trans Am-inspired 302 c.i.d. Those in the know remember the original 350 cubic-inch LT1 introduced in 1970 was a real powerhouse with a hot mechanical cam and 370 horsepower on tap from the factory. Chevrolet’s LT1 engine family evokes all kinds of emotions among Bow-Tie guys.
