Re: LT5 Assembly Project
The Pistons have damage from a screw...apparently the culprit was never found, but he either had partners or possibly bounced around from cylinder to cylinder:
There is however no damage to liners. LGAFF 92 ZR1 #234 Last edited by LGAFF; 03-02-2018 at 07:46 AM. |

Re: LT5 Assembly Project
The only known other issue is the cross threaded bolt for the IH:

Re: LT5 Assembly Project
Step one in inspecting the block, etc was the removal of the balancer.
In order to hold the crank still, I placed a large head screwdriver in the crank position sensor hole, the crank has several notches in it, used for holding the crank still during cam timing. There is actually a tool that is inserted here that snaps into the notch and holds the crank still, but more to come on that. After locking the crank I removed the crank/balancer bolt.

Re: LT5 Assembly Project
I re-used my bolts from my 368 for the 415 build and all is fine.......just turned them a few extra degrees with the wheel on the end of the torque wrench. I also re-used my head bolts on my old Z when I did the ported lpe heads from nj.

Re: LT5 Assembly Project
It seems to me the tool is only needed to locate the proper hole, which I believe they state is at about 51 degress BTDC. The hole for cam timing is deeper that the others, and the pin tool drops flush in the proper notich. I would think that one could use a measured dowel to accomplish the same running a few rotations to ensure that you chose the correct notch.

So you are forcing roughly 160+ ftlbs of pressure on the crank reluctor wheel? |
