I'm starting a new engine build.  Planning on a 408 stroker.  I currently have a 351W bored to 40 over that is 325hp 350tq at the rear wheels.  I would like a little more.  My goal for this engine is still to have a street drivable 500hp.
Right now, I am in the planning stages.  I have a 79 351W block that I'm planning on using.  I currently have a Tremec T5z that will likely need to be changed for the increase in power.  I also have a 9-inch rear with 3.73 gears.
I am currently looking at the following items.  I'm not stuck on Summit, but their free shipping and large selection makes it easy.

I haven't researched what springs are on the AFR heads or if I will need to change them.  I suppose it will depend on the cam I get. 
I am planning on TB EFI.  Maybe MSD, maybe FAST.  I haven't really researched them enough yet to know the differences.  I don't have a fuel return line yet, so I'll have to plumb one into the cobra.
Haven't decided on the distributor or cam yet.  I have an MSD 8478 distributor that I finally have tuned in, but may try a different brand.  I do have a Mallory-brand 6AL ignition box.
My current non-roller-block has a small base circle cam, comp standard roller lifters, and a dog-bone conversion.  I can do the same setup with the new engine or go with the link-bars.  I've heard good and bad things about both setups. The link bar lifters are >$500 now. 
I'm looking for about 10:1 compression. Will keep RPMs under 6k. Mostly a street car with once a year around the track at Harris Hill. 
Whew...  Any thoughts/comments/suggestions?
