i cant get the lower timing gear off the crank. i tried a 2 jaw puller and it just jumps off the teeth everytime. i am going to try a harmonic balancer puller and a bearing splitter if i can get it on there

Verdad Gallardo Let the Machine Shop do that..if you are using that Crank then leave it on there so they can balance it, there is no difference in them Gears with the LS Engines, I beleive the LS7 is the one that's different.

i was just going to hone it and put new rings and bearings in myself with a new timing set. lots of slack in the one i took off. and figure i might as well put the new gears on too... machine shop charges too damn much to do anything. does it really need balanced running the same stock internals?

spoke to the machine shop today $85 to hone it with a 4 stage torque plate hone job or $45 for a 2 stage hone. rods he cant rebuild since they are split caps and not machined, and $50 to vat block
me either...around here we get a standard hone or a hone with torque plates...
As for the rods they make .002 bearings so he can check the big end and if they are out he can hone .002 and you can run the oversized bearings....

is the torque plate hone any better? the for the basic he uses 2 different grits for the hone, for the torque plate hone he uses 4... the bearing surfaces in this engine are virtually unwore. i do have plastigage, any idea on what the specs are?
A torque plate simulates the cylinder head being bolted on the motor, so that the bore is true under load. Honestly, if the bores are good and don't need to be punched out, it should just need a glaze break. I honed mine myself.
Car Rods are different..Compression depends on what Pistons you have, the Head Gasket you are using, and the Chambers on the Heads.
The better question is what Compression do you want and we can help from there..you got the LQ4 right?
