what is the lift and duration on the raby cams that folks are using? i what to get some comparisions on this, will make a chart of varius combos of cams and such.

I understand the desire to scrutinize the cam specs, but IMO you can save yourselve a lot of time and trouble and the possiblity of coming to the wrong conclusion about an option by simply letting Jake make the selection for you based on the performance criteria that he draws from you. He won't miss the mark. No one out there has done more R&D with the T4 in general and the D-Jet 2056 in particular.

You can then ask users of the same cam & combo as yours their opinions of the drivability and overall performance before making your final decision.

The combo you have outlined for your engine is a pretty tried and true one with a lot of folks running it. No need to complicate the process. Stastically speaking if you strike out on your own (by that I mean trying unproven components i.e. cam and heads) you are more likely to miss than to hit the target.

BTW, the #'s on a cam card tell very little of the complete picture, and the #'s from at least one very popular manufacturer of some very popular T4 cams are not what they read on a Cam Dr.

And also, Jake won't likely reveal the critical specs of his cam offerings. He clamped down on proprietary data years ago. You will get a card when you purchase the cam with lift and CL info for set-up purposes. Jake has plenty of business. If the fact that the product he is offering has been exhaustively tested and proven correct for a given application isn't enough for a prospective customer then he just lets them go there own way.
