'68 LT-2 454 / 584hp

Very cool. Imagine what the original would have been worth.

...but, in 1970 when GM finally got round to dropping 454s into 'Vettes they were a lousy 390 horses only. That's why I bought my LS-6 Powered Chevelle SS 454 instead of another 'Vette.

I was NOT happy about it either. To this day I'm still 'ticked'.

There was GM strike in 1970 too; so probably didnt drop those 454s in for awhile....most likely on a Monday morning too

Then why/how did LS-6s make it into Chevelles?

It was plan asinine regardless (not putting 'em into 'Vettes).

thanks for sharing that

Cool story.

The replacement for the solid lifter hi po 427 for 1970 was supposed to be a 454 ci, 460 (rated) horse, aluminum head, single 4 barrel engine with (gulp) 12.5:1 compression. However, it was to be known as the LS-7 (note the slight variation to the LS-6 454-450hp Chevelle). It was never produced, with a variety of reasons/excuses provided. The original LT series engine (LT/1) was a small block, 350 ci engine that was 350/370hp in 1970 1/2 Corvettes & 350/360hp in the newly rebodied Z28. I don't doubt the veracity of this author's story, but the LT engines were small blocks. The "L" series (L68, L71, L72, etc.) were big block 427 (L78 was the 396-375hp), and the LS series were 454 engines.
