Good catch. Well the LT1 cam has an eccentric on it, however there is no provision to bolt up a mechanical pump to the block. TPI and TBI motors had a provision for them IIRC.
OP, he probably ment "LT-1" (older SBC engine) not the "LT1" (newer EFI engine).

there's the LT1 and the LT-1, the LT-1 is a solid roller high compression 350.
From wikipedia
From wikipedia
Years: 1970-1972
The LT-1 was the ultimate 350 cu in (5.7 L) V8, becoming available in 1970. It used solid lifters, 11:1 compression, a high-performance camshaft, and a Holley four-barrel carburetor on a special aluminum intake to produce 370 hp (276 kW) and 380 lb·ft (515 N·m). It was available on the Corvette and Camaro Z28. Power was down in 1971 to 330 hp (246 kW) and 360 lb·ft (488 N·m) with 9:1 compression, and again in 1972 (the last year of the LT-1, now rated using net, rather than gross, measurement) to 255 hp (190 kW) and 280 lb·ft (380 N·m).
The "LT1" designation was later reused on a Generation II GM engine, the LT1.
