Chevy Small Blocks .900\" Camshaft Base Circle for Applications needing additional connecting rod clearance due to \"stroker\" crankshaft. Great in larger c.i.d. street to street\/strip stroker small blocks with good heads. Upgraded valve train components and aftermarket cylinder heads required. WARNING: Camshaft Optimized for use with a Melanized or Nitrided distributor Gear. Not compatible with cast or Steel Gears without similar surface treatments. Failure to utilize the proper distributor Gear will void all warranties and\/or return policies. 4-Pattern Optimize Valve Events Based on Runner Length Increases Area Under the Curve and High RPM Stability.To make the most power from your engine, you need to optimize the air ingested and captured by avoiding valves closing too soon or too late. Any conventional center layout single throttle body or carbureted V8 intake manifold features longer outboard runners and shorter inboard runners, meaning that each valve event should occur at a different moment.\n\u003cbr\u003eRetro-Fit (Link Bar) Hydraulic Roller Lifters\n\u003cbr\u003eThe Camshafts feature four different lobe patterns with one intake and exhaust design for outboard runners, and another intake and exhaust design for the inboard runners. While the four inboard cylinders are all the same grinds, the outboard exhaust openings are two degrees earlier, with outboard intake closings coming two degrees later. This is the first ever use of Technology in street vehicles to balance air\/fuel ratio per cylinder and can net you a possible 1000+ RPM over other hydraulic Rollers and anywhere from 5-20+ horsepower peak to peak, depending on cylinder head flow. The 4-Pattern hydraulic Roller cams are CNC-Machined from Steel billet cores with cast iron distributor drive Gears. The cams also feature a tight lobe separation for both excellent performance and a throaty sound. 1: Cams for '55-'57 engines can be custom ordered. 2: The '87+ Chevy Small Block received provisions for Roller lifters. Most '87 - '93 GM cars came with Roller lifters, but most '87 - '95 trucks came with flat tappet lifters in Roller lifter style blocks. If your block has '87+ OEM-style Roller Cam provisions but does not have Roller components fitted, COMP Hydraulic Roller Lifter Install Kit for '91-'02 Blocks can be purchased. As well as a '87+ OE-Style COMP Hydraulic Roller Cam.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eCamshaft Series: 4-Pattern Small Base Circle\n\u003c\/li\u003e\u003cli\u003eAdvertised Inboard Intake Duration: 299 DD\n\u003c\/li\u003e\u003cli\u003eAdvertised Outboard Intake Duration: 301 DD\n\u003c\/li\u003e\u003cli\u003eAdvertised Inboard Exhaust Duration: 311 DD\n\u003c\/li\u003e\u003cli\u003eAdvertised Outboard Exhaust Duration: 313 DD\n\u003c\/li\u003e\u003cli\u003eInboard Intake Valve Lift: 0.637 IN\n\u003c\/li\u003e\u003cli\u003eOutboard Intake Valve Lift: 0.637 IN\n\u003c\/li\u003e\u003cli\u003eInboard Exhaust Valve Lift: 0.621 IN\n\u003c\/li\u003e\u003cli\u003eOutboard Exhaust Valve Lift: 0.621 IN\n\u003c\/li\u003e\u003cli\u003eLifters Included: No\n\u003c\/li\u003e\u003cli\u003eValve Springs Required: Yes\n\u003c\/li\u003e\u003cli\u003eUsage: Street\/Strip\n\u003c\/li\u003e\u003cli\u003eAssembly Lubricant Included: No\n\u003c\/li\u003e\u003cli\u003eCamshaft Gear Attachment: 3-Bolt\n\u003c\/li\u003e\u003cli\u003eCamshaft Material: Billet Steel\n\u003c\/li\u003e\u003cli\u003eEngine Family: Chevrolet 262-400 c.i. 8 Cylinder (1958-1998)\n\u003c\/li\u003e\u003cli\u003eLifter Type: Hydraulic Roller\n\u003c\/li\u003e\u003cli\u003eCam Type: Hydraulic Roller\n\u003c\/li\u003e\u003cli\u003eGrind Number: 299QS10\n\u003c\/li\u003e\u003cli\u003eGrind Number: 299QS10\n\u003c\/li\u003e\u003cli\u003eBasic Operating RPM Range: 2900-7,200\n\u003c\/li\u003e\u003cli\u003eInboard Intake Duration at .050 Inch Lift: 246 DD\n\u003c\/li\u003e\u003cli\u003eOutboard Intake Duration at .050 Inch Lift: 248 DD\n\u003c\/li\u003e\u003cli\u003eInboard Exhaust Duration at .050 inch Lift: 256 DD\n\u003c\/li\u003e\u003cli\u003eOutboard Exhaust Duration at .050 inch Lift: 258 DD\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eEngine Camshaft\u003c\/li\u003e","brand":"Comp Cams","offers":[{"title":"Default Title","offer_id":52886350791019,"sku":"CCA-12-475-44","price":649.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/CCA-12-475-44-1.jpg?v=1770600533","url":"https:\/\/caautoparts.com\/products\/engine-camshaft-parts-cca12-475-44","provider":"CA Auto Parts","version":"1.0","type":"link"}
