I was running mid 12's all day long at 4000+ft of altitude and running 108-109mph in the 1/4. I thought I must be leaving some HP on the table with the E303 cam. I spent the big bucks, 325 bux to be exact on a FTI Ed Curtis custom ground camshaft .566/.566 lift and 218/224 duration and really didnt notice much if any gains over the E-303 cam.
The E303 cam can present problems such as Idle surge and low vacuum on some cars but it is an excellent performer.
If I were choosing a cam for a car with GT-40 heads I would probably go with the B-303 cam or just leave the stock cam in there with 1.7 roller rockers.
The GT40 heads are better than E7's but not buy a whole bunch.

Yep, i remember you saying that before.
So many people bash the e303, but it sounds good imo too, and im happy with my 107-8 mph traps, eventually I'll have to get rid of it, when i do, im going with a comp cam.
