I've seen the cam I'd like to have on the Crower website but there isn't a kit that comes with everything. I can't find one on any retail website, but that's the way it is when you have a 300 six. Not to many places carry performance parts for it.
You may have to do a mix and match set up. I would call and talk to the techs at crowlers, and find out what psi they want at the seat on your v. springs for that cam, and once you know that you can select from what is out there. I would avoid the Comp lifters. There is a lot of probs with them.
In Comp's defense, they also sell more cams than anyone else so there are more potential opportunities for failure.
And in my experience people are much more inclined to blame someone else when they make a mistake breaking in an engine than say, "I'm an idiot. The break-in instructions specifically said not to use double or triple valve springs during break-in but removing and reinstalling the springs seemed like a PITA" or "I just ran the engine at a constant rpm rather than constantly varying between 2,000 and 3,500 rpm."
Not saying Comp is above criticism, but there are plenty of people who run a Comp cam with no worries. Maybe their QC is subpar but then again people do make mistakes when they rebuild/hop-up engines. Even people who do it well for a living.
When you consider comp is actually #3 in sales internationally, it does say something- stick with a mfg who by percentage has a much lower failure rate.
