400ci COME Alloy engines coming off the production line
After several years of tedious development the steady stream of customers 400ci COME all alloy engines are now coming out of our shop and into numerous customer cars. The refinement and development process has been long winded and very frustrating at times but success with this product is now assured. This latest example has the latest features built into the cylinder head and block castings to maximise performance, efficiency and reliability. This "street" version EFI 400ci engine has our latest design hydraulic roller cam part # CSBR-646, runs perfectly on pump fuel (98 octane) and makes 507bhp uncorrected @6000 rpm and 476ft.lbs torque @4750 rpm normally aspirated.
The torque at 2750 rpm is 425 ft.lbs for an extremely strong engine all the way through a very broard rpm range. This customer requested we also make and fit a custom Nitrous Oxide system for the occassional Drag Strip run. We made a simple but very effective plate system fitted between our Twin Throttle Body and the actual intake manifold. We used the smallest available solenoids and the results are impressive with 633 bhp @5750 rpm and 692 ft.lbs torque @4750 rpm.
This engine in a typical early Commodore up to a VS model would easily achieve better fuel mileage than most stock 5 litre equipped cars and run some very impressive 1/4 mile times with proper tyres and traction. With the N2O it will simply be unmanageable without real drag slicks. The price of this engine outright is $25,000 and if you trade in an EFI 5 litre V8 you would be set back $22,000.
We will also supply any of the individual components to anyone wishing to build their own. The block, heads, crank kit, camshaft and intake manifold are all available individually. As well as this we also offer fully assembled short blocks and fully prepared heads. The engines incidentally can also be fitted with carburettors for simplicity and use in earlier models, for bracket race cars and Hot Rod projects. Remember this engine weighs no more than a Holden V6 so you circuit race enthusiasts building a Commodore for club racing take note.
