MACE STAGE 3 ROLLER CAMS & CHIP PACKAGE TO SUIT HOLDEN CALAIS VT.I 304 5.0L V8

We have formed a series of high-performance camshaft and memcal packages for your VS.III and VT.I 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 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 2000 and 6500rpm. 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 High performance camshaft

Notes:

• 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.
• We have all gaskets available through other ads.
• It is very important that the correct information is supplied prior to ordering a kit so the right call can be made on whether or not our memcals will be compatible or a dyno tune is safer.
• 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.
• Our memcals will not be compatible with strokers or forced induction.
