What does the LS engine installation weigh?
The weight of the LS Series engine out of the crate with the heavy GM exhaust headers removed is 368 lbs. By the time you add the PSRU, radiators, and flywheel,ETC, the installation will be in the same weight an space envelope as a continental 550 or Lycoming 540 installation. (460lbs). I use the battery as a tool to fine tune the weight and balance by either moving it to the tail or putting two batteries in the tail.
