Here's a copy/paste from LS1Tech. I captured the week's progress in this post. First race next weekend if I didn't fv¢k anything up on assembly and Dyno on Thirsday. Motor and trans were recently scattered.
Alright, time to try and catch up to where I am.
So a big part of why I pulled the motor to deal with the heads was so that I could slap a 4x reluctor into this thing which required me to drop the oil pan. Fast forward to a week ago and every online source was backordered on the OBDII LT1 keyway. The local GM dealer was not, so on Tuesday I picked up the correct keyway. I was cautiously optimistic about it.
That's not .100" worth of keyway to engage as much reluctor wheel.
But it's OK. Here is the keyway with a 350 Vortec unit and the chewed up early one I removed.
I probably could have Dremeled down that 350 key, but I'm glad I got the correct OBDII one from the general.
Next thing was to seal up the bottom. First I had to address the busted crank windage tray thingy. Luckily I had one in a spare truck block on the shelf. This would have sucked to grab at the pull and pay.
Much better.
Time to deal with the top end. My machinist scolded me for whiz wheeling everything. We'll see if this thing is still ****ed, then I'll rub it in his face if it is. He suggested 320 grit on a rubber brick as a less bad alternative. It gave a much different appearance and even old machining marks reappeared. Maybe he's not full of it? My halfassery has served me quite well to this point. So I set the heads on the block, and before I cranked them down noticed that the one appeared to suck for oil drainage.
That's quite the wall.
Much better. After cleaning I cranked these down to 70 ft/lb per ARP specs. Next up was the valvetrain. Check out these.
I wonder if one head got hotter than the other? The rockets went back on at 7/8 turn of preload.
Here I was last night with a (finally) fully assembled LT-Juan.
This morning the weather was nice, so I dropped it in before it turned sour around lunch time.
What a sight for sore eyes. Once that was done I ran the engine stand and cherry picker to the hangar and procured some brake pads and a way better clutch release bearing for reinstall. Upon return, I got the clutch and trans reinstalled. I don't know what got into me, but I lifted that T56 back in like nobody's business. I got it most of the way in, propped it with a jack and spun the crank just a smidge, got back under it and that trans about fell into place. Quite possibly my smoothest install EVER. Too good to be true, right? Yep. Forgot the damned fork! So I yanked it back out, popped the fork in, and the trans fell right back into place. Is it better to be good or lucky? No need to celebrate just yet, I have plenty to keep me busy between now and the weekend getting this thing race ready again. But being where I am now feels a damn sight better than this morning with a completely blown apart car.
