Richard I always read your post with great interest. One thing i was really interested in was your post on snappy action cam like the extreme energy which I have in my engine. Now you have me concern about the oil and since you mentioned using a good quality oil such as a formulated racing oil, would it be appropiate using it in a street engine that will see just a few drag races. My 315(bored 305) puts out 303HP and 313 lbs. of torque and I usually put about 2500 miles on each summer. I also need to ask why use your old vavle springs on a new cam break in. Was I wrong using my new springs when I broke in my cam?
