I have used that cam for decades
It was designed to work with ported iron heads as there was nothing else at the time--the thing is is Really works with Indys and better heads
The thing about that cam is WHERE it is installed at
We always had best results installing at around 101 in a 440 CI and 105 in a 500 CI
Now granted we always ran 1/8th mile for the most part but if it is retarded it does not show what it really has to offer
It is THE base line combo for a 440 or 500 CI with Dash 1 Indys--just darn hard to beat and...you have NEVER been in a car that sounded better
First one we ever fired up we switched off right away knowing we had plug wires mixed up--found out it just needed about 5000 RPM to "clear out"
It is an amazing piece --you have to try one at least once
The cam needs lots of spring pressure and Titanium retainers are a MUST--break it in....then up your spring pressure to at Least 150 seat the more the better
It will pull the slober out of your mouth in second gear and high gear is a stunner first time you really lay the wood to it! The sound this cam makes all through the run is just simply stunning!
WHERE it is degreed at makes all the difference--folks that did not like it had in in wrong--out of the box you may have to advance a LOT to get it to 101 or 105 even..leading you to think something is wrong but let me tell you what!!!!!!
Don't quit running Mopars until you have experienced the beast sounding cam of all time
Don't forget the compression more is better
