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?
