Which block for boost?
Thinking of doing a twin build again and think that a stock LS 2-3-7 block with forged internals will work without getting crazy with the big dollar 6 bolt blocks. I would like over 400CI with twin 67's making around 800-1000rwhp and i would like to use a aluminum block to keep the weight down is these feasible? and tuned properly will it last? It will be a weekend'r so not allot of mileage and probably keep the boost turned down most of the time on the street but for those 4-5 times a years i hit the 1/4!

a 4" crank in a stock block will have reliability issues due to the short sleeves in a stock block. If you are hell bent on the extra cubes then get the stock block sleeved you will have a much happier system. even a dry sleeve setup will help the longivity.
I would recomend given your goals that you stick with the stock stroke.
