Re: Cam swap...what else?
Just to add one thing.....the type and quality fuel one uses also may have a significant impact on potential knock retard. Try different fuels (more than once to get a good sampling) and stick with the one(s) that provide the best results. If you want to view KR, you'll have to have some sort of on-board diagnostic/monitoring device. I use a DashHawk on both my Hemi's. I get almost all of my fuel from a commercial refueler (CFN) and locally it's all non-ethanol. If you use reformulated or ethanol laced fuel, it generally will not work as good as plain old "normal" gasoline.
Ws6kid, I hope some of the folks that do the cam swap will post pictures. I've done two now and didn't take one picture. If one does the job without removing the heads (like I did) all that has to be done to the engine is remove the valve covers, rocker arm shafts and front cover. This exposes everything you'll need to get to. By far, IMO, the biggest PITA is removing the radiator/trans. cooler/A/C condenser. When I decided on the Sidewinder cam, it was because of my years on the LX forums, where it has been used very successfully for about the past 6-7 years. Dyno results for the cam/valve train swap only mostly yielded in the neighborhood of 50 rwhp. On mine, using the "rule of thumb" (10 rwhp equals one tenth off ET), my ET's at the drags are right at a half second quicker than with the stock cam.
As far as sound goes, the Sidewinder idles just like the stock cam (smooth), but does have a very noticeable valve train noise.....somewhat more than the so-called Hemi tick.
