Cams going in
Guess I'll throw the cams in over the next week. The HD shop shuts down for the week so I borrowed all the tools. Guess I'll have to take pics for this one too

Gonna give the redshift 575 from zippers a shot and seehow they are.

.575 lift won't work with stock heads..........that's why I'm asking.
Are you doing 103" now too, or waiting?

Will the 575's work with the stock heads? Or are you having the heads done at the sametime?

NEW! 2007-up ThunderMax Cams by Red Shift
ThunderMax cams by Red Shift are ground from 1-piece 8620 steel billets. Red Shift cams provide smooth, linear power with great valve train dynamics. The stroked crankshaft in the 2007 models changes the dynamic from '06 and earlier model TC88 engines, making correct cam choice crucial to avoid engine damaging detonation with today’s fuel quality. Several models are available to best match stock or other installed engine components. All require adjustable pushrods; chain drive only. Head work required unless otherwise noted as a bolt-in cam.
575-HS: 96" and 110” Engines - Bolt-In
Zipper’s Part Number 413-926S
[ul][*]Designed fore use with stock, unmodified heads[*]Great bolt-in upgrade for stock 96 or 110” engines[*]Works well in 103" conversions with dished pistons[*]Increases torque and horsepower across the board [/ul]

Good Luck with that.................I wouldn't do it.
.575 lift with stock valve springs is a lot................even though Doug at HQ told me I could use the 0039's with stock heads he also didn't really recommend it.
Under .550 lift is pretty much all that is generally recommended with stock springs..........to do .575 is really pushing the limits and reliability.

RE: Cams going in
I was kinda wondering about that too.... It seems a bit on the agressive side for the stock springs.
I'll be interested to hear what ya think.
It seems peculiar that a cam is OK with 96 & 110", but not 103.....
As for the 110, forget it. If you really wanna go bigger, just do the 113. I've heard nothing but bad about the 110's.
