Holden Stroker Kits and cranks 
Highest quality, lower prices!
The COME Racing Holden V8 and V6 stroker cranks and kits are the most popular in Australia by a huge margin. With great strides in production efficiencies we are now offering our cranks and kits at hugely discounted prices...PERMANENTLY. There is now no excuse for rebuilding or modifying your Holden V8 without stroking it to a 355ci or 383ci capacity. All COME cranks are fully machined on our Berco production crank grinders to maximise accuracy of journal sizes and perfect indexing to ensure journals are exactly 90 degrees apart for maximum engine smoothness and power output. You do have alternatives with other cranks on the market, some at even lower prices than ours. If you want the best quality and strongest cranks on the market and at the best prices you now have no need to go by price alone. There is also no need to compromise on buying a cheaper kit with lower power potential pistons or other such components so you cannot upgrade power safely a little down the track when you get greedy for more. All our kits for street/strip applications feature 4340 grade steel connecting rods with ARP bolts and the toughest performance pistons in the industry.
355ci Holden V8 Stroker kit, comprising our proven nodular cast iron 3.484" stroker crank with perfectly indexed rod journals, journal sizing taper and ovality tolerance under .0002" variation. Our 4340 forged steel 5.7" "I" beam conrods with ARP bolts fully machined on our Sunnen powerstroked rod hone to under .0002" tolerance. World famous Keith Black Hyperuetectic alloy pistons in your choice of oversizes and compression ratio options from 9:1 up to over 11:1 Pistons are fully fitted to rods and aligned. The finest moly ring set from either Wiseco, Hastings or Speed Pro is supplied along with premium King rod and main bearing sets. The whole rotating assembly is computer balanced to under 2 gram tolerance with all pistons and rods match weighted. kit price...$1995.00 Note: This kit is designed for power levels up to 500 bhp.
Instead of numerous confusing different kits we have simply made the above 355 kit our baseline version with the following optional components and pricing. Basically, you choose the options you need and add the extra cost to the baseline kit price.
Options:
1) 355ci billet 4340 steel crank. The absolute most accurately made and strongest crank available ANYWHERE for the Holden V8. These cranks are CNC machined from a round solid bar of the finest 4340 grade steel and finished on our production Berco grinders for the ultimate in accuracy with final heat treatment to provide the toughest wear surfaces possible. They are ideal for those who just want to have a steel crank in their engine at a bargain price, for boost engines, N2O and endurance competition and serious Drag Racing applications they are a must. ADD...$1200.00 to the above kit price to include our billet steel crank in your kit.
2) COME 4340 steel "H" beam rods. COME rods are not your run of the mill mass produced imported rods so common on the market. We make them from the finest 4340 grade steel forgings which are fully heat treated and shot peened, add ARP 7/16" capscrew fasteners, precision finish hone both big end and small ends on our Sunnen powerstroked rod hone to under .0002" tolerance for size and taper. All sets are match weighted for ease of balancing and are stroker friendly to ensure minimum block clearancing is required. To option our "H" beam rods in your stroker kit ADD...$500.00 to the above kit price.
3) WISECO forged racing pistons. For those needing a custom application piston or the ultimate strength of a forged design you simply cannot surpass the world famous Wiseco brand. We have these pistons in all our current race engines and all our customers street and race engines with incredible reliability. The best part about these is we always know the consistency of the machining is second to none. This makes every engine builders job that much easier. We have optional Wiseco pistons for all applications from high compression street or race to low compression boost applications always on the shelf. They are supplied with Wiseco's matching moly piston ring sets in balance match weighted sets. ADD...$990.00 to the above kit price to include Wiseco forged pistons in your stroker kit.

383ci Strokers...fact and fiction...
Our competitors would have you believe that Holden 383 stroker engines.....
Wear out more quickly...won't have high rpm potential...won't make more power than a 355...wear out cylinder bores due to higher piston side loads...are much more expensive to build...will blow up more easily...will use more fuel...amongst a host of other lame excuses as to why you should buy their 355ci stroker kits and ONLY build a Holden to a maximum of 355ci
FACTS...383ci Holden engines easily last as long as any other Holden V8...We have built customers 383's since 1993 some of which have done over 300,000kms and they are still running. We've had at least 100 of these engines back in our shop over the years for rebuilds and absolutely normal wear patterns were obvious. No unusual "side loading" of bores to create rapid wear or split bores. Our powerful engine packages like the "Ultimate" or S.S-3 versions with large port cylinder heads and unrestricted intake manifolds make insane power levels and their biggest feature...incredible torque. Well above anything any 355 could ever hope to achieve. They also achieve these power levels at lower rpm levels for more long term reliability and life potential. YES, they have always been MORE expensive to build. Now with our new pricing levels the gap is very marginal. Only slightly more block clearancing is required over that needed for the 355. Particularly with our EFI 383 engines customers report lower fuel consumption than even stock 5 litre engines when driven sensibly. With so much more torque on hand large throttle openings are simply not required to rapidly accelerate the car. This keeps the engine in closed loop mode much longer actually reducing fuel consumption. If you need any more convincing look at our own Torana's 383 race engine...over 500 1/4 mile passes making over 850 bhp and the crank is still the same one from way back in 1996. Look at Darren Parker's VP SS Commodore reliability results shown in a recent weblog entry below (scroll down for details). Finally look at Eddie Tassone's world record holding twin turbo 383 Holden V8 with over 1890rwhp, 8.1 second 1/4 mile times @ 178 mph. Ask Eddie what he thinks about COME components and particularly our Holden 383 cranks. NONE of these race 383's doing well over 7000 rpm has EVER "blown up".
