The last 5 cams from flat tap pet to roller HAVE FAILED due to MANUFACTURING DEFECTS. How embarrassing for quality.
Here is Ken's number. 1(360)256-7985
Run a cast iron gear and a full base circle- if you got the clearance. If you can afford it a 4/7-2/3 swap will help.
Funny, I run Comp stuff and haven't had any issues......getting ready to order another one as well.....and these aren't mild street cams either.... .900+ lift rollers.........
Instead of bashing a company, just make suggestions......Are you sure it wasn't user error that caused the failures???? Any proof? I call BS.....
As to what cam to run, there are several companies that can get you the proper cam for your combo. Chris Straub, Comp, Crower, LSM, Bullet, Mike Jones, Howards.........Best bet is to call all of them and talk to them. Be honest with what you have and intend to do, and make a decision based on what they tell you....If it were mine, I'd run a solid roller myself. Hydraulics are good for street stuff, but I'd shy away in a racing application unless the rules limit you to them. No reason to run a flat tappet anymore on anything, and I wouldn't by one of those either, unless again I'm bound by the rules. A solid roller will make better power over a broader range, even in the milder grinds. For a gear, can't beat the Lunati ever wear gear. You can run it on any cam you want, and they last. A 7/4 swap, or 7/4, 2/3 swap cam will only benefit your combo if it's optimized for it. They are not a magic bolt on and for many combos they are not needed. Save your money for things that will do more for your dollar...For the intake, you can run a dual plane, but there are some single planes out there that will run circles around a dual plane, even at lower rpms. Again, a bit of research here will pay big dividends. There are several head guys out there that are very familiar with those heads, Like Chad Speier, that can also help with manifold and cam selection....
