This marinized Chevrolet ZZ502 came in my 25 Daytona and ran 85mph on GPS @ 5,200rpm spinning a 28 pitch labbed Bravo 1. I don't know what modifications have been performed to it, but I know that it is right around 570hp, not the stock 500+, as I installed a dyno'ed 540 that put out 740hp and I only gained 9mph using the same propeller (spun it 6,100 @ 94). Using the boat speed calculator on BAM's website, it shows this motor to be at 570hp. I have no idea how many hours are on the engine, but the prior owner said he had less than 40 hours on it since he put it in, and I've put about 60 hours on it. It always ran flawlessly for me, and was running great the day I pulled the boat out of the water to do the engine swap. This is a perfect motor for someone looking to upgrade from an older 454 or 502MPI. I am selling it complete with headers, or complete without headers. Price with headers is $7,000.00, price without is $6,000.00 - contact (510) 813-1683 for more info. PMs will not be responded to - call the # provided.........
