Hello Hi Tech

It is not very often I voice in on issues on this site as there are many well educated and experienced individuals that respond to inquiries. This is the case here but just for fun I thought I might put in some thoughts.

When it comes to which type of the four lifter designs commented on here is best is really not an single answerable question. Each type has it's own merits and short comings. To say one is best is short sighted and doesn't leave thought to the merits of the other designs. There is no magic pill here.

I would submit that the ball is really still in your court as you must define exactly what you intend your car and your engine to be able to do.

How will you drive the car?
What will be those driving conditions?
What kind of power you want the engine to make? Be real here.
Where does engine maintenance fall as a priority?
How many running hours do you intend this engine to last before maintenance?
And many other questions need answers.

These may seem silly questions that, of course, would seem to have obvious answers. But I submit they are not. If you take the time to seriously consider your expectations and realistically look at the constraints your driving environment place on your car and engine you will find that the question of camshaft selection is very complicated one. The better you understand your engine expectations the better you can establish the type of cam the best works for your driving needs.

Allow me to qualify my opinion. I run a selective engine shop that focuses on building engines for Cobras, High end Street rods, and Muscle cars. Each engine that leaves my shop is built to the exact standards that the customer and I agree services their specific needs and their cars' specific needs. Experience has taught me that owner expectations and actual engine requirements are never the same and most of my pre-engine building time is spent defining what this customer wants. This can take days of conversations not just two or three calls. I insist on meeting the customer face to face and going over every single factor that this customer wants to cover and explaining to him why or why not his ideas will work. At the price of high end engines, the importance of my reputation to me, and satisfaction of knowing the customer is truly pleased with his end product this front end time is my highest priority.

Just as no crate engine can specifically service a car and owner needs. No single cam design can be considered good or bad. It is simply too generic of a question. Define your needs then ask the question.

Good Luck with your car.
