Magnacharger Radix Cam help Ok so the blower is in
So far I have a set of Harland Sharp 1.7 Roller Rockers(not installed), will need springs and pushrods as well.
The CAM ???
It needs to be daily driveable and compatable with a 2500ish(stock HD) stall converter and should have a good chance at passing CA smog. I honestly don't think I need anymore off idle HP/TQ (no traction), but don't want to lose any either. I'll be getting some Mid or Long tube headers before the Cam goes in, my exhaust is very good from there back.........whats the good combo?
I don't know much about Cams at all, but have made the following observations:
Blower Cams seem to have at least -10deg overlap (-10 to -18 being average). Also the more Neg overlap there is, typically = a smoother idle or is associated with Cams of smoother idle (usually on a 114-115 LSA).
Are these observations correct?
Cams I've been looking at:
Dur @ .050 214 intake and 222 exhaust
Lift is 545 intake 550 exhaust
Lobe seperation 115
Intake centerline 111
DUR @ .004" 278*/ 286*
DUR @ .050" 216*/ 224*
* LIFT .551/.551
LSA 115*
thanks for the help

I like the off the self Comp grind 54-412-11 works good for blower and emission stuff.
212/218 .522/.529 114 the 54-414-11 would probably work good also 216/220 525/532 114. I ran the 412 in my 01 didn't get a chance to put my whipple on it but I liked the cams drivability and power right out of the box ( all I did is drill the throttle body out to a 3/16's and she ran fine). Good luck!
