i got a 347 ls1 with 11 to 1 CR, heads and cam, and a 3900 stall..... and i was wondering if it is safe to run this set up on a stock fuel system... i dont plan on racing at all for the moment im just wondering if its safe to just cruise it..

 

Might consider upping to 30# SVO injectors at least. The stock injectors started running well over 100% duty cycle shortly after 400 RWHP, on my car at least. You can push them past 100%, but its a bit of a gamble IMO.
