THESE days it\u2019s pretty easy to get blas\u00e9 about horsepower. With turbocharging making it all too easy to build a 1000hp street engine, it can be hard to get excited about anything less. But we were pretty pumped to see this 540ci big-block Chev engine on the dyno at Dandy Engines<\/a> the other day, because it\u2019s using these new big-block heads and it makes 800hp naturally aspirated.<\/p>\n Now you may be wondering what\u2019s so exciting about new heads for a big-block Chev V8 \u2013 there are literally hundreds of different cylinder heads available. Well, for starters, these heads are made in Melbourne, Australia by Competition Induction Design (CID), which is a joint venture between cylinder head gurus John Konstandinou and Nathan Higgins. The heads use a symmetrical port design to keep the intake runners pretty close to the same length; naturally this requires a specific intake to suit, and CID makes them for both standard 9.8in-deck-height big-blocks and 10.2in tall-deck blocks. They\u2019ve also changed the combustion chamber to a more efficient design, which requires custom pistons, but it\u2019s worth it. Out of the box the CNC-ported heads flow around 420cfm at 0.850in lift, and almost 400cfm is available at 0.700in lift. They also do a full competition version that flows close to 500cfm.<\/p>\n When the donk arrived at Dandy Engines, it made 693hp with Brodix heads and a solid-roller cam. Changing to the CID heads, custom pistons (same compression) and a solid flat-tappet cam yielded just on 800hp, and yet it remains a streetable pump-fuel engine.<\/p>\n \u201cThis would be the perfect engine for an HQ,\u201d Frank Marchese of Dandy Engines says, \u201cand in fact that\u2019s what it is going into. If you want a little extra, give it a shot of gas and you\u2019ve got 1000hp!\u201d<\/p>\n
