mine are nasty performance fuel rails..i got mine from a buddy in town..his bro wrecked his firehawk and i got the wiring harness from it..the wires to the injectors are all color coded and ls1 harness has the same colors plus numbers..easy to hook up..by the way you could have put a better pic of my engine in the first pic..

OK, gathering parts for the swap. Intake is on the way, Going to use stock LS1 injectors, Summit fittings and lines, some kind of billet fuel rails 
, looks like I can use my stock water pump with slight modifacation.
Do I need a car map sensor? What relocation brackets? Different Accessories?
EDIT: Just need idler relocate bracket and can keep accesories
Anything else???
