W2 Heads for a 340 Block...

Well like I said before, I want to use a 360 block, I believe the 408 uses a 4" crank, I am not sure if using a steel or a cast is of much importance, I don't plan on going over 500HP, and from what I have read the cast should handle that. I have been trying to find something on the pros and cons of the Hyperutectic KB pistons, and the Forged KB pistons. I am not good with cams as far as what to use and what not to use. I know I'd like to have a nice lobe at ideal, and I'd like to launch nice when I do take it racing. I have looked around and all the short blocks seem to come with forged rods, it just differs on which brand they use. I would probably be using a mech. water pump, with an electric fuel pump. I don't know on which carb to use, I was thinking some where around 850ish, I am a pretty big fan of the Quickfuel carbs, but I have also heard good things about Demon carbs and various others. I have heard good things about the victor intakes as well, and depending on the port work, it would probably be a better choice to go with something on those lines. I will be using an 4speed OD set up, so I am not sure on what kind of clutch or anything to use to be able to race it on a regular basis. As far as the suspension goes, I have a set of super stock springs that I am going to be putting on the car, and then I have a stock BBP front end, and I plan on getting the TB replaced, they are for a /6 right now. I'd like to be able to take my old lady out on the town and have a conversation with her while driving, but still be able to run in the 7's when I go to the track, I don't mind high 7's just as long as I am in that range lol. So with that being said, what are some things to consider, and some places to start looking to get the motor together?

It's much easier to get a true street car into the 7's with a 408. Money very well spent. I just did a true street 408 with W2's, solid street roller cam, victor intake unported, 950, 1 5/8 step headers and 9.8:1 and it made 550's HP. You could tame that down to 500 and pick up the low-midrange power and keep the rear gears on the high side (3.23).
The heads were ported, but not heavily.
