Hardcore Mercrusier 496 bASE & 496HO complete NEW engine completey rebuilt with FORGED piston and rods
The GM/Mercrusier 496 is a great engine but has some flaws! So here at Hardcore we do things a little differently
and take care of the weak spots in these engines by installing aftermarket Scat 4340 rods with ARP bolts and Wiseco
Pro True forged pistons with Moly rings, Heads get NEW stainless steel valves, Crane Gold rocker upgrade.
we blueprint every engine to our strict
specs for marine applications

Specs
496 Block Thermally cleaned and magged, bored and honed +030 then square decked and mainline checked
Crank magged and checked for straight and micro polished STD/STD
Rods Scat forged Pro I beam 4340
Pistons Wiseco Pro-Tru forged with coated skirts
Rings Wiseco Moly
Timing set Melling roller
Cam Base or HO
Lifters Comp Cams
Oil pump Melling HV
Head gaskets Cometic
Gaskets Fel Pro
Heads thermal cleaned and magged, New stainless steel 1 piece valves, 4/3 angle valve job and surfaced
Crane gold roller rockers and ARP rocker studs
Mercusier Marine oil pan
Mercuiser intake manifold

This engine is assembled but there are different cam gears and timing covers for cam sensor depending on year manufactured, we have all configurations and can change cam gear and timing cover to suit your application! this is important as the engine will not match your ECU and will not run without correct configuration!

Exchange $8500
No exchange $10,000

Yes it will run with no changes to your stock ECU!

We can change out camshaft to a Comp or Crane and increase power if needed but will require ECU flash

What all power increase can you make with this? Just a cam swap and stronger all round engine or, are you doing any Head and intake work etc for more power?

Is 500-600hp attainable on pump gas and still low compression?
