Comp, Lunati, Mopar?

I grew up within a few miles of Comp,Lunati,Ultradyne,Lazer,Bullet,etc. It's funny how things change and guys work for one company them another,etc. I always(almost) use Bullet for my cams as the customer service is better than the others,but that comes with 30+ years of this stuff. Tim @ Bullet has been around for years and he will give you good advice and a high quality product which is not always the case with other companies.If we are talking flat tappets and more than a mild lobe the P55 cores are the best. Most shelf grinds are on standard cores which can lack some heat treat depth.
