Biggest mistake ever- lunati cams

MerlinsMopar said

Well, I definitely made the issue way harder than needed be. Took the heads of and to another performance machine shop nearby and he took the measurements and popped two .060 hp shims in the spring pockets and got my installed height down to 1.710. The springs were showing 125lb but will relax once it's broken in. Also told me to forget about breaking the cam in with only the outer spring and damper. Said it was a total waste of time. So my session has officially come to an end. Thanks to everyone for your replies. I can finally get this motor completed.

Even 125 is a bit low.

I used to never, ever pull the inners. Now I do it religiously. I don’t care if it’s 100 on the seat. It’s not that hard to pull the inners, fire it off, run it in and then drop the inners back in and do another 15 minute run in.

These lobes are all pretty much quicker than what we had when I was a kid.

One junked lobe and you’ll wish you’d have done everything and then some because the cost of unscrewing the issue is way more than the time it takes to pull and install the inners.

I lost a lobe (just one) on a Comp cam on the dyno. And that was on a single spring. No inner. It’s a giant PITA to pull it down, clean it, get another cam and lifters and put it back together and then back on the dyno.

IT SUCKS. And it costs time and money.

I always say don’t step over a donut to pick up a dog turd, but you can also say don’t be pennywise and pound foolish.
