Sold D1 and now going twins
 

2000 Silverado I have complete LS2 minus heads and intake. I hve a Fast 102 im afraid to push much boost through. I also need yead recommendations and wwmhat a stock LS2 block is worth. Turbos, rear, and everything else will be built.to support more that my goal.

Sell the FAST intake. Purchase a NNBS intake and be better off, save money and get performance.

LS2 engines are worth what someone wants to pay. People in the north here still try to get 2-3k+ for a LS2 because it must be worth gold.

Are you asking what year engine you should buy? The typing here is poor, either your half a sleep or on struggle street with a phone trying to say what you mean.
