It offers a camshaft duration of 222 intake \/ 230 exhaust with a lift of .635\" intake \/ .635\" exhaust, a 112 LSA, and a 107 ICL. This camshaft is designed to work within a heads and camshaft package, with Texas Speed's PRC ported cylinder heads and a .660\" dual valve spring kit. The camshafts are designed on a SuperFlow 902 engine dyno to provide optimal power curves while maintaining piston-to-valve clearance. For enthusiasts seeking maximum streetability and stock-like idle quality, this truck camshaft option is recommended, retaining excellent low-end and mid-range power suitable for towing.\n\nThis camshaft package requires a DOD delete kit (#25-LT1DODDEL-KIT) as it does not utilize the factory DOD\/AFM system. The Gen 5 L83 and L86 engines utilize Variable Valve Timing (VVT), and this camshaft is designed to work with that system, with Texas Speed offering VVT camshafts and phaser tuning tables. It is important to note that the largest camshaft recommended with a factory torque converter is the 25-TSPLT1VVT-SV (222\/230 duration), as additional duration may affect streetability without an aftermarket torque converter. Potential gains of 100+ HP can be achieved with corresponding modifications. The product description also includes a disclaimer regarding a known issue with factory GM LT cylinder head castings where valve seats can fall out, which can lead to engine damage. Texas Speed \u0026amp; Performance recommends purchasing their aftermarket LTx cylinder heads to mitigate this risk.","brand":"Texas Speed \u0026 Performance","offers":[{"title":"Default Title","offer_id":52663969120568,"sku":"25-TSPL83TR-3","price":422.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687140517.jpg?v=1784331355","url":"https:\/\/store.motormia.co\/products\/l83-stage-3-camshaft-222-230-635-635-112-lsa","provider":"MOTORMIA","version":"1.0","type":"link"}
