i remember an article a while ago in gm hi tech mag ,that gave alist of ls1 specific tools for building ls1 engines , anyone know of ls1 specific tools and there make/# thnx bob

 

kent moore makes a whole ls1 kit, every special tool for the ls1
they also make a time-sert kit for the whole engine

 

thank ,what is a time-sert kit bob

 

Nothing real special for just building engines Bob. The usual stuff. Some people prefer to use the GM designed tool though. Definitely get a brass hammer (for removing main caps - they get stubborn and the brass will not damage them)

 

So far I've been able to persuade the main caps out with ease, just a little "encouragement" from a handy object here and there. Most of 'em come out easily if you stick your fingers in the windows and lift up evenly.

I'm about to rig up a crank spinning jig on the bench and a ghetto journal polisher to remove a touch of surface poop from a crank that sat in some water :puke: At least it hasn't pitted it yet, so it's quite usable without needing to be cut .010"

 

the kit comes with drill bits and taps for every hole on the block.
when you pull/strip a thread on aluminum you have to drill bigger, tap, and screw in a time-sert. time serts are like screw-in threads that you lock-tite in place.

 

oh ok its a heli coil set for these engines thnx bob

 

not helicoils, they are hardened steel inserts not slinkee-like inserts

 

helicoils are hardened stainless steel that work fine-have used them to hold exhaust manifolds with no problems

 

exhaust manifolds ok....try bolting a head down with one. good luck
time serts are solid metal
