What you guys think of the 507A1 Cam from Lunati
I wanted an Old Faithful cam hybridized with solid rollers. but while I exercise my patience , I was contemplating running a solid roller or even a Solid of Hyd Flat.
Lunati 507A1 : Solid Roller Cam. Good cam for real street or mild bracket racing applications. Needs 2500-3000 RPM stall converter, head- ers, 9:1+ compression ratio and 3.55+ gearing. Fair idle. ;Advertised Duration (Int/Exh): 278/285 ;Duration @ .050 (Int/Exh): 242/249 ;Gross Valve Lift (Int/Exh): .556/.556 ;LSA/ICL: 112/106 ;Valve Lash (Int/Exh): .020/.022 ;RPM Range: 2500-6000 I like the 112 LSA since I spray a 200 shot. My built is a 461 using SD CNC heads ( 260 cfm), HO Intake , Q-jet, 1 3/4 dougs , full 3" exhaust, built Th400 Continental Jim Hand special converter and 3.08 gears, may go up to 3.36 or 3.42 if needed.
