[QUOTE="99svtvert, post: 5500614, member: 22962"] Started the project this weekend to replace FR500 springs with special double helix; and to install solid lifters with double rollers. I should gain 30-40 RWHP at 8,000 RPM. (440-450 RWHP) fo the FR500 Cobra 4.6. Remember I have Oliver I-Beam Rods and a 9 Quart Canton Oil pan with a custom clearanced windage tray. The oil will not be an issue. I am now using Royal Purple. This is [I]Just for fun[/I]; you know - I'm not worried about adjusting valve lash; infact I may not even need to, after the initial adjustments. I pulled the valve covers today and I have to tell you the FR500 valvetrain is immaculate after 19 months and 9,400 miles; looks as new as the day it was installed. No flipped followers either at 7,600 RPM. Much more later with pics. [/QUOTE]
