The hydraulic roller camshaft comes from Crane, as will all of Shaver's valvetrain weaponry. Starting with Crane PN 11HR00110, the cam boasts .548-inch intake lift and .567-inch exhaust lift with 1.5:1 rockers. With the maximum-allowed rocker ratio of 1.6:1 for Chevy-based entries, the lift numbers get a bump to .584 inch (intake) and .604 inch (exhaust). Don't rush right out and order this cam for your own car, though. It's a special grind to fit the roller bearing-equipped cam bearings in the block, so the sizes are different. Why did Shaver choose a hydraulic roller over a solid, flat-tappet design? "Under 6,500 rpm, with only a 1.6:1 rocker ratio, I can easily make more power under the curve with a hydraulic roller than with a solid, flat-tappet cam. All day, any day, no question. It'll end up being 230-240@.050 on the intake side, and 240-245@.050 on the exhaust side. Lift will be about .600-.610 inch. That's probably all it'll take, and it's a streetable combination that should start pulling hard where you guys begin testing at 2,500 rpm." Naturally, Shaver will test several profiles to fine-tune his entry; this is simply where he'll start. View Related Article
