383 Holden reliability and performance
383 Holden EFI...9.98 E.T @133 mph
Darren Parker and his VP SS Commodore ran an excellent 9.98 ET and backed it up with a 9.99 finishing runner up in the recent Summernationals at WSID in Sydney. Just last weekend Darren did it again by winning the West Coast race in Perth. The COME 383 has done almost 500 passes in Darren's Commodore. The engine was freshened a 2nd time late last year and still has one of our nodular cast cranks and Keith Black hyperuetectic piston. On this most recent birthday we decided not to be greedy and change the rods and pistons. 500 passes is a lot of work and we can't complain about "street" type components not giving us incredible value for money. In fact, the cast crank looks like new, has no cracks (after all that work) so it went back in. A new set of COME "H" beam rods and custom Wiseco forged pistons were also fitted to complete the upgrade.
This engine is based on our 383 Ultimate EFI Holden but has optional solid roller cam and valvetrain, makes 550 bhp on our engine dyno and crosses the finish line just over 7000 rpm every run. You won't find find too many combinations as effective and reliable as this for a weekend Bracket Racer application or for street strip use with it's normal hydraulic roller valvetrain and pump fuel version putting our over 480 bhp year after year.
If you are building a Holden V8 as we've said before, give the 383ci capacity stroker a strong consideration. Everyone immediately opts for the 355ci strokers without realising the incredible benefits of the 383 version. To entice everyone considering which capacity stroker to go for we have the following special deals to consider:
1) 383ci 9:1 compression Stroker kit including our 3.750" nodular cast centre counterweighted crank, "I" beam 4340 steel forged conrods, Keith Black hyperuetectic 9:1 compression pistons (up to 9.5:1), moly rings, rod and main bearings and the whole assembly is fully balanced internally...$2750.00 delivered anywhere in Australia.
2) 383ci 10:1 compression Stroker kit includes everything the above kit has plus features higher compression Keith Black hyperuetectic pistons and your choice of press fit or fully flaoting COME "I" beam con rods. The kit is fully balanced internally...$3000.00 delivered anywhere in Australia.
If you are one of those people who must have the best and want either kit to include our latest billet 4340 steel crank just add...$1500.00 to either of the above prices.
There are even bigger deals available for purchases of crank kit and any of our other components at the same time. You will really save money if you order crank kit, our EFI Twin Throttle Body intake manifold and cam, lifter, chip combinations and/or our latest 2006 VN style alloy heads. This also takes the guesswork out of combination building and final tuning hassles. Basically, machine your block, put the whole lot together and turn the key.
For those not wanting to do the work themselves we have some great fully built engine combinations to satisfy every budget and power need. You also need to consider our all alloy crate motors. Our complete 400ci all aluminium engines are on the shelf ready to deliver. We have carburettored "Street" 400ci alloy engines ready to go for $20,000. These killers make a totally streetable 500 + BHP and 500+ ft.lbs torque...ON PUMP 98 FUEL. EFI versions are also ready to go for $22,000 These engines use the same cranks, rods and Keith Black pistons found in Darren Parkers race winning engine, so you know they will last many many years in street and occassional strip applications with virtually maintenance free hydraulic roller valvetrains.
LS1 crate motors
We haven't forgotten the late model Commodore owners either. To make performance upgrades easier we have embarked on a crate motor program for the LS1/LS2 style engines as well. Initially, we will be offering easy upgrades for LS1 5.7 litre owners in the form of 408ci short motors. By retaining your complete LS1 top end and simply adding one of our "brand new" 408ci short motors you instantly have 550+BHP and 550+ft.lbs torque to play with with stock LS1 heads and intake manifold. Our 408 short blocks come completely assembled and blueprinted with our ever popular 4.00" stroke nodular crank, new crank angle sensor, "I" beam 4340 steel full floating con rods, custom Wiseco forged pistons, moly rings, new rod and main beaings with the whole assembly fully balanced internally and all fitted into a brand new GM 6.0 litre alloy block. These short blocks include our now famous COME LS1 camshafts (you have a big choice of grinds) and timing set. Short block price, outright, delivered in Australia...$8000.00 Add $500.00 for "H" beam conrods.
Other combinations will be available soon, including turn key outright engines and long motors. Call or email if you have any specific queries about our latest deals.
