Are O2 sensors needed?

I am modifying a '98 harness for a 240 swap and want to know if I need the O2 sensors?

you will definetly want to keep the o2`s, and make sure there are no knicks in the pink wires that run to them!

if you dont want to pay for o2 extensions and havent bought new o2`s yet, you can just by vette o2`s. they have plenty of extra length to them. something like an 03 zo6 o2 would work.

There are quite a few people that run without them... those are track only cars though. The o2 really only do something at idle, other then a funky/rich idle the car should run fine.
