620FME 620HP - ZZ572 V8
GM MARINE ENGINE
This is a drop in replacement when you want more power out of a GM big block engine. This Flagship marinized, aluminum headed, 572 CID performance engine, is like the one that GM installed in Jay Leno's Buick.
It comes with a 70 AMP marine alternator, Header Style exhaust system, GM injection that is controlled by a MEFI4b ECU, AZSpeed intake manifold, Heat Exchanger and Oil Cooler, PS Pump and Raw Water pump.
