425HP --> 525HP
Here's another interesting tidbit...The Vortec HP3's racing the circuit have the same cast crank that the HP1 does.(So will all the 496's come next year).........

From what I've read and heard the Merc 525 is a better engine but should also cost more than the GM HP3. I believe the Merc motor has better internal components, pistons & rods.
BTW, upgrading to the Merc 525EFI from the HP500, wholesale cost difference is $4,000/engine.

At 525 hp and 5200 rpm do you need the 'better' internals of the merc or if the cast holds up why overbuild.
Numbers control costs. Gm sell more 496 truck engines in one day than Merc sells in one year. They have how many million miles of testing and usage to see if the cast crank holds.
Reggie tried to do his own engines several years ago and merc squeezed him and the project cost him over a million.

Cobra,
That's kind of what I was thinking, too.
Perhaps, some GM Vortec racers can chime in...How many failures have there been with the HP3's and what kind...
From what I've heard so far, there have been no bottom end problems whatsoever. Just minor problems like hoes leaking and overheating and chit like that.
Steve, you out there?

In SVL one and two it is the GM engine the one to have.
The guys that were running mercs switched to GM.
I wonder what changes merit a $4000 price change?
Where is the popcorn?

Baha Daze,
It was what Ricks said earlier about the 500 to the 525 merc cost.
I think what GM did this year was tremendous, If racers like and win with it ,it sells. It beats any proving ground.
