Upgrades for 2019!

Well guys its been a while since I've done one of these. When I built the motor for this car it was a toss up between 3.8 and 4.2. I decided on 3.8 and have been happy so far. Well like everything else that has been done to my car an opportunity presented itself to acquire a known good 4.2 and I couldn't resist. After receiving the motor it apparently had a small amount of metal pass through it at some point so my hope that it could be ball honed and ringed was a pipe dream lol.
The motor is being prepped first .004 had to be removed from the cylinders so the pistons are getting a special .004 coating and custom rings from total seal. Then while I'm in there I am having calico coated rod main and can bearings installed. Once it is all done I plan to pull the 3.8 and transfer all of the top end, dbl roller timing set and all the other goodies over from the existing 3.8. I am also going to send the clutch to McLeod to have it checked, install a condenser core for the eventual reinstall of the ac and do more wire tucking. The other upgrades I am doing are a Cadillac ATS brembo brake upgrade which I will discuss in detail. I am also having AJE upgrade the lower a arms while I'm at it because I noticed they were bent while preparing to pull the engine.
 
Well so far the updates I have completed are.
4 piston Brembo brake upgrade
Pulled old 3.8 had it inspected cleaned up and sold to David Galo
4.2 was re honed .004 phase new rings gapped at .027 piston walls coated with abrasive coating at .004 new calico coated bearings installed in rods mains and can.
Motor has been reassembled.
Purchased a spec aluminum flywheel I ordered a new insert for it and inspected the McLeod clutch. Everything looks good and I am assembling it and checking the hydraulic slave spacing again tomorrow.
Motor is going back in the car Thursday.

Well the 4.2 is in and running but I have to pull the transmission because the clutch is causing some tranny grindage issues.
