Lemme ask this one to the Guru's of Timing ..I seemed to stump a few people on this one, hoping someone in here may have come across this one before.

Sayyyy... you re-build your FD engine and use 2nd Gen housings (cheaper) but the distance between the leading and trailing plugs are different to that of the leading and trailing plugs on an FD housing ... what timing do you use ????

..FD timing or FC timing ?!?!? or some where in between the both ???

What is standard FD timing and FC timing anyways ??

TIA,
