I have non sealed 604 crate. It is now a 355 with the heads milled a little. It does have a little bigger cam and heavier valve springs. It also has 1.5 and 1.6 roller rockers. Is complete from intake to oil pan with no distributor. It has the harmonic balancer, water pump and pulleys. It also comes with an externally balanced bert flywheel and coupler with the hdt drive pulley. This motor runs great with est 500 hp on gas. It has 16 nights on it since rebuilt. I reccomend a set of rings and bearings. It was completely new in 2007. I ran this as my back up for a ump mod. It works really well in the slick.
