This new publication is in the same vein \nas others within this series. Des Hammill goes into detail of how to \nbest extract more power from the DOHC engine without spending a zillion \ndollars.\n\nWhat I liked about this publication is that it \nfocuses closely on the race-winning D-type version engine and reminds us \nthat it wasn't too dissimilar to the production engine but was still \npowerful enough to propel the car to just under 180mph. The publication \ngoes into detail on the separate components of the engine including the \nblock, crankshaft, conrods, cylinder head, camshafts, ignition, \ncarburettors and exhaust system. It tells the reader that like other \nengines, the secret of the XK engine is the cylinder head. We're advised \nthat the best standard head is from the XJ6 Series 111. Luckily, that \nhead fits the 3.4, 3.8 and of course, the 4.2 engines, provided that you \nplug two of the coolant holes for the smaller engines. \n\nIf you're into Jaguars, this is a most useful \npublication.","brand":"Veloce Publishing","offers":[{"title":"Default Title","offer_id":44937325642008,"sku":"B05027","price":28.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/9813\/3831\/files\/9781845849603.jpg?v=1772258609","url":"https:\/\/www.midlifeclassiccars.com\/cs\/products\/how-to-power-tune-jaguar-xk-3-4-3-8-4-2-litre-engines-speedpro-series","provider":"MidlifeClassicCars.com","version":"1.0","type":"link"}
