Andrews 48H or Red Shift 525?
Hi Everyone,
Planning on replacing my stock cam this winter and I've narrowed my choices to the Andrews 48H or Red Shift 525 grinds.
I'd like to hear back the opinions from other members who've installed either cam.
'08 Roadking 96"
Stage 1 air Intake
Stock heads
V&N Propipe
SERT Dyno
Thanks

Installed the 48 in a couple of Stage I 96" motors with good results. I have not installed the Red Shift 525 looking at the specs, I am thinking the Red Shift might be a fun cam but, like I said, have no personal experience with that cam.

What's intriguing about the 525 is the early closing intake valve and the big difference in centerlines. I'm thinking that the 25 degree overlap combined with the 0.05" difference in lift will keep the tq line high and to the right.
But, at a price difference of nearly $75.00, I might become color blind to the corrected/final dyno chart. Lol

EDIT: I see you will keep the heads stock, so the added lift of the 1.7 ratio rockers won't be much help. Did the '08 Roadkings come with ACR heads? I think you will need compression releases with the 525 as CCP is about 190psi.

We've never used one of the Zipper cams here, but have installed the 48 many, many times.
Folks always seem to be very happy with the power.

Not really, higher lift but with a 36* intake close, the motor will be a turd compared to the 525; less CCP than the stock cam.
The OP is running stock heads and flow doesn't increase much between .400" and .500" lift and flattens at .500" lift., so .475" lift would be about right for stock heads.
