Overall Assessment

Customers have confirmed that this engine is specifically designed as a Jeep replacement. It is not a plug-and-play motor, as it needs custom wiring harnesses, which aren't ready made. It is also confirmed to have a Multi-Displacement System (MDS), and is considered a drop-in replacement for late model automatic transmission cars. Nonetheless, customers caution that it isn't ideal for muscle car swaps or any usage that would necessitate an 'off the shelf' Mopar Performance wiring harness. Despite these restrictions, customers have expressed that with the appropriate knowledge, it can perform effectively. It's important to note the absence of the MDS in OEM Part number 68303090AA.

After buying this engine from Speedway I discovered it was for a Jeep replacement only and no wiring harnesses are being made to run it. The Speedway Techs were no help at all, but they did graciously let me return the engine for a full refund. I'm sure with the proper knowledge and investment this engine would work. I wanted an engine that was a simple plug and play with an off the shelf Direct Connect harness, which from what I've learned, this one is not.

Buyer Beware - Has MDS.

This is a 392 6.4L Crate Engine WITH MDS (OEM # 05038749HA) meant to drop in replace on Automatic transmission late model cars, not for muscle car swaps. This engine has MDS, no "off the shelf" Mopar Performance wiring harness is available and have to have one custom made with 12-week delivery. Please note this is NOT OEM Part number 68303090AA that comes MDS Deleted.
