Only thing I have left to put on my ls1 is the harmonic balancer so how do I go about it

 

Either get an install tool from one of the sponsors or get a threaded rod, a stack of washers and 3 or 4 nuts and press it on. DO NOT try to use your old balancer bolt to press it on. You may get lucky but most likely you will strip your crank threads.

 

pm sent about the install tool!

 

Do yourself a huge favour....only install an ATI if going u/d. It will help the harmonics of your engine ten fold.

 

 

WHY! Do a search on broken chains....also Kurt Urban re ATI pulley.

Only weird to the uninformed.
