Sleeker, I would also be interested
in that combination if it could be purchased in that price range.
Greg

Just as Sleeker mentioned-- I built my 588's everything brand new for $12000, incl dyno testing (no exhaust) they made 704 hp @5600, and 698 tq max @4800. I think with a little more tweaking we'll see another 25 hp.

Oh and the torque was 655@3300rpm --pretty flat!

This engine has a lot of attention (ZZ572/620hp -Deluxe); I am also looking to obtain one at dealer cost.
I would love to find the facts on any marine conversion issues.
The cam? --- O.K. as is or Not?
I'm in fresh H20 so the aluminum corrosion issue is not a problem for me.
I heard these engines were delayed again?....

Joe

Yes, they have been delayed again.

Can I hear an Amen!
