ok well im having trouble with my motor, it seems to be running ruff and out of timing.... being that said here is the specifics of my motor...

b18c1 block
ls crank and rods
p73 pistons
ctr crank pulley
itr oil and water pump..

b16 head
gsr cams
450cc dsm injectors
itr headers
cai

so my question is when i do the timing do i need to set the crank pulley on one of the three notches or do i still keep it on the lone TDC mark?? i have a basemap for the setup.... Thanks in advance....

 

first i would verify mechanical timing is correct. ignition timing with a non-advance timing light would be in the middle of the three notches.
