I ran the Ford Racing .472/.496 lift 214/224 duration cam with a C4 and 3.55 gears. I liked it very much. If you are going to switch gears soon, I would recommend that cam. I also had the .448/.472, 204/214 cam. If you are not going to be swapping gears soon, that is a torquey cam and is matched to the Performer intake.
Go for a double roller timing chain. They last longer than stock chains. Any brand will do.
Just a few unsolicited comments.
1) The drag strip is a totally different world. There is no such thing as a "decent street/strip cam". If there is a performance level(ET) you desire, name it, and we can reccomend a combination that will get you there.
2) Most of the top cam companies sell a big kit that includes cam, springs, lifters, retainers, locks, and timing set. They also have tech lines with very knowledgeable techies to help you determine exactly what you want.
3) A bigger cam, headers, carb, and manifold will very often rob you of your previous low end torque. Unless you want to leave every stop light at 4000+ RPMs, be careful what you ask for. This is what I meant by no such thing as decent street/strip.
