Description
CONVERSION KIT FITS
MerCruiser Chevy based big block V8 engines 454-502 CID, fits sterndrive, inboard and V-drive. Especially designed for the low capacity raw water pumps used on sterndrive engines. Kit will NOT fit most engines with high mounted alternators such as late model OMC engines. Some engines have fuel line routing and fuel filter location that must be changed slightly. Heat exchanger is 5 1/8″ x 22″ long and fits within overall length, width, and height of most engine conversions. Heat exchanger extends from the inside of the starboard exhaust manifold towards port side clearing most high mounted power steering pumps if any. See above illustration. Plastic expansion tank mounts either on front of heat exchanger or if space is limited on vertical surface next to engine.
NOTE: This system will not fit 454 or 502 Magnum MPI engines. The picture below is a 7.4L MPI (aka L29).
