CROW CAMS CAM AND CHIP PACKAGE TO SUIT HOLDEN 304 5.0L V8

We have formed a series of high-performance camshaft and memcal packages for your VN - VS.II Holden 5L V8. Designed to deliver real-world horsepower gains of up to 35%, our cams are intended to wake your 304 right up and put the enjoyment back into driving.

Stage 1 Kit: Improved torque and economy

Our stage 1 kit provides a power gain of 15% between 1200 and 4200rpm. Perfect for towing, normal driving, and highway cruising. It’s also ADR compliant.

Contents:

• 01 X Crow Cams High performance camshaft
• 01 X Tailor made memcal
• 01 X Assembly lube
• 01 x 100ml Run-in oil additive
• 16 X Crow Cams iron lifter.

Stage 2 Kit: Improved mid-range power

We recommend this kit be used in conjunction with at least a 2.5” twin cat exhaust for maximum performance. This package provides a maximum power gain of 20% between 1900 and 5000rpm. This increase has been achieved without sacrificing any noticeable low-end torque or drivability. This kit can also be ADR compliant.

Contents:

• 01 X Crow Cams High performance camshaft
• 01 X Tailor made memcal
• 01 X Assembly lube
• 01 x 100ml Run-in oil additive
• 16 X Crow Cams iron lifter
• 16 X Crow Cams performance valve spring

Stage 3 Kit: Improved top end power

This camshaft kit must be used in conjunction with a full free-flowing exhaust system and minor head work for maximum performance. It provides a power gain of 35% between 2400 and 5500rpm. Despite the excellent high-performance characteristics of this package, the engine remains tractable and responsive at low speed while adopting that old-school choppy idle. A standard torque converter can be used on automatic-equipped vehicles, but we recommend a 2000rpm stall converter to enhance acceleration.

Contents:

• 01 X Crow Cams High performance camshaft
• 01 X Tailor made memcal
• 01 X Assembly lube
• 01 x 100ml Run-in oil additive

Notes:

• Camshaft must be run in as per the supplied instructions, including running the cam in with the standard valve springs.
• Memcals in these packages are calibrated by Mace and we have strict guidelines in terms of what modifications our memcals support. Your setup's compatibility will be determined on the basis of the filled out application form. In case of non-compatibility, you can either change your setup to a compatible one or we can supply you with the package without the memcal. *CLICK HERE* to download the blank application form and send it back to info@maceengineering.com.au
• Our memcals will not be compatible with stroker kits or forced induction. For these cases it is recommended that the vehicle gets a custom dyno tune to ensure it is safe.
• Genuine broadcast memcal number (4 letter code on sticker attached to factory fitted memcal) will be required in most cases to confirm the operating system.
• One bottle of engine oil additive lasts for just 500 km.
• Pushrod length will require checking if heads have been skimmed or block has been decked.
• We recommend dialing in all aftermarket cams using a degree wheel to ensure that they’re phased correctly with the crankshaft. You can do this by using our 8" or 11" degree wheel listed in other ads.
• Gasket kits to suit this engine can be purchased through other listings.
