Default 402 build questions

I haven't posted much on this forum, but I truly envy some of you guys and the things you've done with your vehicles. Anyway, now that I'm done sucking up, I have a few questions about a LQ4 build up that is going in my 1995 Impala SS in the next few weeks. I'm debating on a 402ci stroker. I'm not completely sure what the stroke is on the stock crank, but with the 4.0 inch stroker crankshaft, would I need to get shorter connecting rods due to the increased length that the pistons are traveling? Or would i be better off going with pistons with offset wrist pins? I'm going to be running the Racetronix LT1 fuel pump with this setup and I'm thinking that 42# injectors should be more than enough for the 402. If you have any suggestions, (besides use search) I'd like to hear them.

Thanks. Any idea where the best place to purchase one would be? I've ordered from Scoggins-Dickey before but I'm not sure if they have any kind of package deals.
