hello all

i have been having problems with the ls3 coils on the 408 i have had built recently(converted from ls1 coils to ls3) . the problems i have are as follows:
.misfiring at low rpm
.hard cranking when starting after engine is hot . sometime also get pre-ignition

i have changed the starter motor as i was told that was the problem .
The ls1 coil wires and plugs were used , could this be the problem.
The tunner has told me that he has changed the dwell timming .
The tunner is telling me to go back to the ls1 coils , i can't understand this as the ls3 coil is supposed to be a better coil.
so if any one has the tables for the dwell timming and the following or has come across similar problems , i would like your assistance.
