I seem to remember reading, possibly in the SCG article, that the LS-7 Corvette was to get the same 3X2 intake setup that was on the '69 435hp engine, or was that idea scrapped early on?

Chris,

There were two 3x2 454 cid engines planed for 1970, coded LJ-1 and LJ-2. They were basically 454 versions of the previous year's L-71 and L-68 engines and are documented in the 1970 Corvette Assembly Instruction Manual. If I recall the notes in the 1970 AIM correctly, these options were terminated late in the 1969 calendar year. The LS-7 was distinct from these two engines and would have used a single vacuum secondary four barrel Holley carburetor.

In addition to the LS-7/LJ-1/LJ-2 options, a fourth engine, LT-2, was also planned. This would have been a 454 cid version of the ZL-1... Aluminum block, Aluminum heads, etc. It must have been killed early on as there is no mention of it in the AIM.
