can a stock LS1 block handle 600-800 hp with a power adder? Looking to start my build up and need to know if a new stock block can hang or if I need to get a C5R block. If the stock block can take it I'll be in touch with valvegod in the next week.

just get an iron 6.0 block. no need to spend soooooo much on the c5r block.

 

I've been doing pretty good so far, with no plans to replace the block during the upcoming build up.

goal after the build is 800 RWHP <img src="gr_grin.gif" border="0">

Is that a stock LS1 block? If it is I saw your site and it seems to hold boost pretty good
