You got me, Trout.
Could be the 500efi was the start of the "parts box" HP500's versus the bolt-on HP500's.

Of course, ALL engine blocks are "precision CNC machined" when new regardless of where they come from. And the Merc Rods with the logo machined in them haven't been around that long though.

GM Announcement to suppliers late 2003:

"The 496 cubic-inch Vortec HP3 8100 crate engine will deliver more than 525 horsepower and more than 560 lb-ft of torque "

There is a marinized crate engine available too but I don't have a part number, HP rating or cost figure. The above engine sounds like a nice machine and heavy on the torque too. Obviously the HO Merc offers is a lower output version of this. The 496 can do much more obviously for much less $ too! Is this the new C-6 doggie too?

http://www.pistonheads.com/news/defa...p?storyId=5764

it's an old article; suprises me the merc HO is what 425HP?

any further info appreciated.

Well, guys, not to burst any bubbles, but I have a 2001 hp500efi on the stand right now, and there's nothing but GM in there as far as the short block goes......... JE pistons, GM crank, 7/16" rods...... nothing you can't order right out of the GM performance parts catalog. The oil pump pickup is welded tho as somebody said on here.

not that GM doesn't know how to build a motor tho..
