LS7
Hybrid 427/7.0 litre/454/Turbo/Supercharged etc.
This is based around the massively strong Darton MID (modular
integral sleeve) block assembly which many believe is superior
to the famous C5 block (see the Darton link at top of page).
The Darton LSX block uses thick, immensely strong yet ductile,
removable wet liners with patented cooling features at the
top of the bore just under the cylinder head, right where
the cylinder is hottest. Coolant can also circulate across
the block via drillings in between the cylinders, thus stabilising
temperatures around the bores. Darton liners have been designed
and proven for reliability in ultra high horsepower applications
including nitrous or turbo applications (some using 45 lbs
of boost), top fuel dragster and tractor racing where cylinder
pressures are extreme and detonation is never far away. Unlike
the LS7 block a damaged Darton liner could easily be replaced.
The LS7 block with it's thinner liners could easily be a write
off! This is a full on 'true' hand build using GM hand tooling
and digital equipment to any final build specification. This
engine will never see an air wrench. As standard we include
the top of the range Callies Magnum crankshaft which we have
hand fettled to our specification. We include special order,
custom made billet titanium rods (not the inferior LS7 forged
items). Our rods weigh appx 500 grams and have a full width
little end as opposed to the tapered/wedged LS7 rod end. We'd
never use the thin crowned, weak LS7 cast aluminium pistons
and instead, provide quality forged items featuring additional
dry skirt low friction treatments and ceramic coated crowns.
They are tailor made to match the donor block we work with.
We include file fit Total Seal gapless rings. Our crank &
rod bearings are coated with a dry film lubricant for reduced
friction when running and minimal wear when cranking the engine.
LS7 heads with titanium valves are included (we like those)
or we could supply aftermarket parts.
Our custom LS7 'short runner' intake manifold is included,
single or twin plenum with your choice of throttle/s assembly.
Our plenum accepts twin copper chargecoolers as well as water
injection. The plenum can also be modified to accept a supercharger.
In LS6 trim the plenum was flow tested in the US by Race Engine
Development and outflowed a ported FAST .
We can supply and fit dry sump equipment for this engine
build. Please take the time to read the Darton
Link, this product is impressive.

£18'000 or £16'000 with stock plenum and throttle.
