The machinist called me and told me he CC'd the heads today. They came in at 66 cc which, according to the calculator, will bring me to about 9.9:1 compression ratio, which I think will be good all around for the parts I have and what I'm trying to do with them.

The compressor cover is a stock BW cover that has an enlarged inlet with antisurge holes, and some internal porting done to it. Its a concept turbo so we're going to try this first and if it doesn't work then look into modifying a race cover.

I've been slacking on the updates too, I know.
So its been a while since an update. I've been working a ton on this thing so haven't had much time to post pictures, but heres where I'm at with it.
Got the car out of storage and got everything set up to slam it together in a weekend. So all that was left to do was put the cam in and put the heads on the engine and it would be ready to drop it. Pulled the cam out and found the cam had a bad lobe, which explains the dead cylinder on it when it was still in the Tahoe. But that was no big deal. I looked at the cam bearings and they all showed copper. Pulled a main cap and the bearings weren't too bad, but didn't look great. So at 5pm on a Saturday I was able to track down new main, rod, and cam bearings. I spent the weekend rebuilding the shortblock. Checked all the ring gaps and they were pretty consistent. .024 top ring .026 2nd ring. I didn't adjust them at all. Pretty good for a 3.78" bore I think.
Heres the cam that came out. 90k mile DOD/AFM engine. Ran great, good oil pressure. Just a dead hole on number 2.
Shiny new bearings for a shitty old engine.
Damn bearings ruined my weekend haha.
Got the shortblock all together. Went to put the lifters in and found out I need ls2 lifter trays. Ugh. Gen 3 lifter trays don't work in gen 4 engines, but gen 4 trays work in gen 3's. But the gen 4 trays I had were for DOD/AFM lifters so they wouldn't work with my LS1 lifters. So I started the weekend with only a shortblock and ended the weekend with a shortblock.
Got the trays from the dealer the next day and threw the longblock together.
Then dropped that longblock in the car finally.
Started bolting everything back together. Man that turbo is looking good in there.
Seemed fitting haha
And finally got it running. Had a hell of a time getting it running. Ended up finding out that the cam sensor wasn't reading. I had repinned the 12v power to the cam and crank sensor to 5v, then swapped the "A" and "C" cam wires around which is the needed mods to convert to 58x. Was having issues getting it tracked down, but called Woody at Holley tech and he got me all set up to do a system log and figure out that the cam sensor wasn't reading. I have to say that the system log function is a stupid cool feature on the system. Essentially you can take a datalog of the cam and crank wave forms to help narrow down your sensor issues. So I have it running in batch fire mode right now but I did get a new Delco sensor that I still need to put in, as I'm thinking the cheap Napa sensor is causing my issue. So here it is after I got it running and parked it out front next to the boss' Magnuson'd CTSV.

Been driving the car around for the last week or two working on the driveability tune. Have a nasty driveshaft vibration, which I had last year too, so I'm considering having a driveshaft built for it. Otherwise I got up early Sunday morning and me and my dad took my car out to a local all ford car show. I managed to sneak in with the hood shut lol. Definitely got a lot of looks though.

The 1.32 seems to work fine on my 5.3, but I also have some decently ported heads, higher than stock compression, and a billet compressor wheel. Essentially the turbo is for a 6.0 based forged setup that I'll get around to building, but we'd like to see how this turbo does in the meantime on a 5.3.
