TBI fuel lines

Are you wanting to know only if the fuel fittings are the same, or if the lines will fit over the motor?

I suspect the fittings are the same, as to the length, I'm curious as well (350 should be shorter I think, but might have enough in them to work anyways) as my dad got a 454 setup for his 454, but the lines were no good on the donor truck, and 350 lines are everywhere.
 
We did the 454 TB swap on the 350 in my buddy's '88 K5 without changing the fuel lines, so you should be good there. We did have to pick up a cheap TBI spacer and grind it down a little to clear the bigger butterflies on the 454 TB.
 
I'm running the factory lines with the 454 TBI unit and no issues.
