actually I've installed enough custom ones for customers to know they have always exceeded the ots cams that were in the motors, when a combo is matched it works very well.....and who you have custom grind your cam really does matter, if in 10 min the designer comes back and says ...ummm okay I'm done...then might as well be getting an ots cam

custom cams matched with the right heads ported and the right valve springs will give you some good numbers.

Portmaster- im guessing that 581 hp is at the flywheel?....what you hitting at the wheel?

... there is no such thing as a "one cam fit all". A real custom cam designer will spend more than the time a phone call takes when ordering such....... to cover all the bases.... end user screw-ups or bad info?.... "that's another 20 bucks".

Don't know yet. The car isn't finished (but closing in)Because I'm using a C6 and a 9 inch currie I'll be lucky to get 475 to the wheels. Thats just being realistc. I'm using a 3500 stall converter so I'll be in this engines sweet spot as the converter flashes.

I absolutly agree and don't discount the advantages of a good custom grind. The secret to having your cam in a hurry is spend several hours on an extensive tech sheet for the car and KNOW exactly what you have and intend to use before filling out the tech sheets and then make the call. It doesn't take long when all the information is right in front of you and the cam designer doesn't have to call you six times. Before I order a custom cam I have everything including the frontal area of the care measured. The only thing I had to guess about was the actual weight of the car. I spent three days finding another car built as close to what I was doing and took the scales and weighed the car. If it took someone 10 hours to figure out the grind you can bet it would cost more than 300-500 dollars to figure it out and supply the core and grind it.
