Hey guys, Im getting ready to drop my +-430hp LT1 into my FD (LSx too hard to find over here) and my "ever so trouble free" rotary was also 428hp.

Im running a 255lb walbro pump w/press. regulator. Stock LT1 injectors cleaned and serviced.

The fuel lines running from the pump to the rails, should they still be fine, are they going to be 'just good enough', or should I get some higher pressure lines?
Does anybody know what the stock FD fuel lines are rated at?

Thanks in advance,
James
