5LT is like (or is the same as) the LT1 then? Still a good motor...but not quite the same beast as the LS1.
The LT1 was always a 350ci(5.7) as far as I know.
The 305 was used in the following cars:
* 1976-1993 Chevrolet Caprice (includes Impala)
* 1976-1979 Chevrolet Monza
* 1976-1979 Chevrolet Nova (also GM X-body clones after 1976)
* 1976-1992 Chevrolet Camaro
* 1976-1988 Chevrolet Malibu, Chevrolet El Camino, and Chevrolet Monte Carlo
* 1978-1992 Pontiac Firebird
* 1978-1980 Oldsmobile Cutlass (US Market only, Canadian market after 1980)
* 1991-1992 Oldsmobile Custom Cruiser
* 1981-1987 Pontiac Grand Prix
* 1975-1979 Buick Skylark
* 1977-2003 Chevrolet/GMC Trucks, SUVs, Vans
* 1991-1992 Cadillac Brougham
The 305 variant of the small-block Chevrolet had a displacement of 5.0 L (305 in³) with a 3.736 in (95 mm) bore and 3.48 in (88.4 mm) stroke. The 262 was considered underpowered for use in vehicles with a wheelbase greater than 110", so GM engineers decided to increase the bore diameter from 3.671" to 3.736" and increase the stroke from 3.10" to 3.48" (from the 350). Some performance enthusiasts have noted a marked resistance to performance upgrades on the 305 because of its small bore, poor selection of aftermarket cylinder heads, and the relatively high availability of 350 in³ engines.
Induction systems for the 305 included carburetors (both 2 and 4-barrel), throttle-body injection (TBI), tuned-port fuel injection (TPI), and sequential fuel injection (GM Vortec).
After 1996, its usage was limited to light trucks and SUVs as the Vortec 5000.
