In fact, one of the most frequent questions fielded when customers call our tech line is, \"what camshaft will give my car that mean-sounding idle?\" In an ongoing quest to provide you with the performance and sound you demand, the COMP Cams engineering team proudly introduces the Thumpr series of camshafts. The Thumpr camshafts are a new series of hydraulic flat tappet camshafts. The lobe profile and grind characteristics of these new Thumpr camshafts use a combination of early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. \u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eApplication: Flathead Ford (2 Gear) 239, 255 c.i. 8 cyl. 1949-1953.\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e  \u003cli\u003eCam Style: Mechanical flat tappet\u003c\/li\u003e  \u003cli\u003eBasic Operating RPM Range: 2,200-6,100\u003c\/li\u003e  \u003cli\u003eIntake Duration at 050 inch Lif 235\u003c\/li\u003e  \u003cli\u003eExhaust Duration at 050 inch Lif 249\u003c\/li\u003e  \u003cli\u003eDuration at 050 inch Lif 235 int.\/249 exh.\u003c\/li\u003e  \u003cli\u003eAdvertised Intake Duration: 275\u003c\/li\u003e  \u003cli\u003eAdvertised Exhaust Duration: 307\u003c\/li\u003e  \u003cli\u003eAdvertised Duration: 275 int.\/307 exh.\u003c\/li\u003e  \u003cli\u003eIntake Valve Lift with Factory Rocker Arm Ratio: 0.368 in.\u003c\/li\u003e  \u003cli\u003eExhaust Valve Lift with Factory Rocker Arm Ratio: 0.364 in.\u003c\/li\u003e  \u003cli\u003eValve Lift with Factory Rocker Arm Ratio: 0.368 int.\/0.364 exh.\u003c\/li\u003e  \u003cli\u003eLobe Separation (degrees): 107\u003c\/li\u003e  \u003cli\u003eIntake Valve Lash: 0.012 in.\u003c\/li\u003e  \u003cli\u003eExhaust Valve Lash: 0.014 in.\u003c\/li\u003e  \u003cli\u003eComputer-Controlled Compatible: No\u003c\/li\u003e  \u003cli\u003eGrind Number: 287TS7\u003c\/li\u003e  \u003cli\u003eValve Springs Required: No\u003c\/li\u003e  \u003cli\u003eQuantity: Sold individually.\u003c\/li\u003e  \u003cli\u003eNote: Performance street\/strip, needs higher compression and aftermarket heads, rough idle.\u003c\/li\u003e \u003c\/ul\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44555450810679,"sku":"CO41-601-7","price":1391.3,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/61573.jpg?v=1780416889","url":"https:\/\/enginemaster.com.au\/products\/comp-cams-co41-601-7-ford-flathead-v8-1949-53-thumpr-solid-camshaft-235-249-050","provider":"Engine Master","version":"1.0","type":"link"}
