This is a 454 Mercruiser Magnum MPI (Mark IV) rebuilt from the ground up. It is from a COMMERCIAL PARASAIL BOAT, but is currently sitting on the engine stand at the mechanics... it has only 6 hours on the engine in the shop and needs another few hours of break in after it is installed in your BOAT OR CAR OR TRUCK. VIDEO AT http://www.youtube.com/watch?v=N0iSvla2OtY I WILL DISCOUNT THIS ENGINE 50,000 pesos if you want to install it in your car, and just keep all the parts that are necassary for a boat..... For more detailed info visit this link: http://www.sulit.com.ph/index.php/view+classifieds/id/3132408/454+Mercruiser+MAGNUM+MPI+%28Multiport+Injection%29+650+Horse+Power
