I have 2 questions: First. I will be installing my GT40 heads, GT40intake and E303 cam(which I haven't buy) to a stock 5.0 bottom end.
Are there any specifications like the "cam degree" specific for this cam or anything else I should do to avoid "guessing"? I know that PVC is a must but what else?
My second question is: What approx. hp and torque should be there after this H/I/C swap supported by shorty headers, cold air intake, 73mm mass air and 70 mm throttle? I will be using 3.73 or 4.10 gears.
Thanks for your help guys....

When installing an E Cam I would just install it straight up which is just dot to dot on the timing gears. Install a new Timing Gear also.

As for estimated HP, with proper tuning, you will probably see about 250-260 RWHP.

OK. So it will just be like installing a factory cam. No advancing or retarding the cam at all. Sorry to ask but I have never installed an aftermarket cam like the E.

Correct. Depending on the cam you can advance or retard. With the "E" Cam, there is no need. Are you using factory Rockers or Aftermarket Rockers?
