As fas as I know, the EC is a further stripped down 040. From Wikipedia: "Versions of the '040 were created for specific market segments, including the 68LC040 which removed the FPU, and the 68EC040 which removed both the FPU and MMU. Motorola had intended the EC variant for embedded use but embedded processors during the 68040's time needed nowhere near the power of the '040, so EC variants of the '020 and '030 continued to be common in designs."
The Amiga 1200 had an EC020 and ran fine, but at least on paper the EC40 should be even slower than the LC40 as fitted to Performas.
