A little bit of an update: thanks to Grandpa Biden and the newest economic stimulus package, my tentative completion goals have been pushed up to this summer; if at very least have the engine in the car (but not necessarily driving around). Anyway, simply put, I'll be buying more car parts to finish things.
In the meantime:
I've received my Furches Performance oil pan, and have it loosely bolted to the motor.
I sent the heads off to the machine shop for a once over and everything came back as good (I still have to go pick them up).
Pressure washed the long block with some degreaser and aluminum brightener before teardown to try and clean it up a bit. There was still some heavy staining, so I opted to rattle-bomb the block and front cover with some cast aluminum, even know it'll never get seen by anybody except me (shrugs).
Stripped the LS4 engine harness (and most of a 2000 truck harness) down for complete rewiring into Monte.
I talked with Brandon at Furches Performance and opted to just one-stop shop for all my engine stuff. I'm getting his full DOD-delete package (including gaskets and hardware) in addition to a custom grind cam. This leaves me with just incidentals like hoses, fluids, etc to get at this point.
Did a little bit more grinding on the motor mount to clear the output shaft. It didn't take much more and now I'm debating using it and just adding a spacer bracket to to bolt the two together, or just do a one piece motor/ trans mount. Thoughts?
