alright guys, installed new sprocket on crank and put the marks at 12 o clock like the manual said to. piston is at tdc but it seems like to matter how much i adust the sprockets on the cam and crank i cant seem to get them both perfectly in line and still get the chain on! startin to get frustrated to i guess my question is how close does it need to be? right now the cam is at 12 oclock perfectly and the crank is like 1/2 a tooth lenght to the right. before i put it back together is that close enough for the HEI to compensate or do i need to spend another day bustin my knuckles?
