Updates!
My circle D converter came in, went with the 245mm pro single disc billet, 3800-4000 stall, 1/8 head space, installed transmission, body mounted dipstick, acdelco dex6, arp bell housing bolts, AN-6 cooler lines to the radiator, will eventually add in an external. For the crossmember, I ended up using the Amazon one that recently came out, it’s a double hump, this thing is extremely beefy, but it fit flawless. I used the energy suspension 3.1108g trans mount, with the rubber cut flush, and not using the preload plate, it also helped lower the driveshaft angle down. I ran into clearence issues on the passenger side header hitting the frame using jegs g body ls swaps, so busted out the BFH and did some clearence work, everything lines up and sits straight with no needless stress on the tail shaft housing. I purchased a cheap 5.3 cold air intake kit, and flipped it around to the driver side using a longer 4 inch silicon elbow (there were mounting brackets I cut off, will smooth them out and repaint it) I had a custom steel 3.5 inch driveshaft made, came out to about 49 inches with 7/8 inch travel play and a spicer yoke, for the 12 bolt, I needed a conversion u joint, 1350 series in driveshaft end, and 1330 end for the pinion flange. Getting the tires swapped out tomorrow, just need to weld a shifter mounting plate inside, and install it , run the headlights, tuck some wires, and should be ready for its first test drive soon!
