We install forged pistons and rings etc specific to your build ie they aren't usually 'off the shelf' items. You get a custom cam package, ARP studs, a double roller timing chainset and gears, 1.8 rockers plus other performance parts which may be chosen by you. You can pick your performance head package as well. All the internal parts and clutch assembly etc are dynamically balanced prior to assembly. We are happy to build an engine using parts supplied by yourself. So you can save money with this option especially if you have a donar engine.

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.

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