Let's face it--few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. 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. \u003cstrong\u003eSpecs:\u003c\/strong\u003eApplication: Ford small block Windsor 351ci V8 1969-96.\u003cdiv\u003e Cam Style: Hydraulic flat tappet \u003c\/div\u003e\n\u003cdiv\u003e Basic Operating RPM Range: 2,200-6,100 \u003c\/div\u003e\n\u003cdiv\u003e Intake Duration at 050 inch Lif 235 \u003c\/div\u003e\n\u003cdiv\u003e Exhaust Duration at 050 inch Lif 249 \u003c\/div\u003e\n\u003cdiv\u003e Duration at 050 inch Lif 235 int.\/249 exh. \u003c\/div\u003e\n\u003cdiv\u003e Advertised Intake Duration: 287 \u003c\/div\u003e\n\u003cdiv\u003e Advertised Exhaust Duration: 304 \u003c\/div\u003e\n\u003cdiv\u003e Advertised Duration: 287 int.\/304 exh. \u003c\/div\u003e\n\u003cdiv\u003e Intake Valve Lift with Factory Rocker Arm Ratio: 0.501 in. \u003c\/div\u003e\n\u003cdiv\u003e Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.486 in. \u003c\/div\u003e\n\u003cdiv\u003e Valve Lift with Factory Rocker Arm Ratio: 0.501 int.\/0.486 exh. \u003c\/div\u003e\n\u003cdiv\u003e Lobe Separation (degrees): 107 \u003c\/div\u003e\n\u003cdiv\u003e Computer-Controlled Compatible: No \u003c\/div\u003e\n\u003cdiv\u003e Grind Number: 287TH7 \u003c\/div\u003e\n\u003cdiv\u003e Valve Springs Required: Yes \u003c\/div\u003e\n\u003cdiv\u003e Quantity: Sold individually. \u003c\/div\u003e Notes: Not designed for fuel injected applications.\u003cbr\u003eNote: High performance street\/strip, needs 9:1 CR, 2500+ stall, intake, gears, and headers, rough idle. \u003c\/div\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44549741379895,"sku":"CO35-601-4","price":624.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/61513.jpg?v=1780416866","url":"https:\/\/enginemaster.com.au\/products\/comp-cams-thumpr-hyd-camshaft-235-249-050-co35-601-4-suit-ford-351w-v8-1969-96","provider":"Engine Master","version":"1.0","type":"link"}
