If you call him Richard will go through all your specs and help you pick a cam that will do what you want and actually work. They are ground on comps blanks by comps. I received awesome A+ service from them and they went above and beyond to make me happy. I received a cam that was ground on a short snout blank. not what I ordered. Richard got it fixed in 10 minutes and comps sent me a replacement in 3 days. Very good company and I had zero complaints. 507/507 cam is a 4x4 cam that you can not order from comps. I spent around 1000.00 one afternoon with them and when it went wrong no excuses they fixed it. was no fault of richards but he fixed it with no bitching, no B.S, no nothing just fixed. made me loyal customer. Try that with hughes Indy etc
