The Transmission and converter will be here today, hope to get time tonight to put it in, maybe tomorrow.
I am wanting to have the transom working properly before attacking the water pump and vacuum pump install. I want to drive a while tuning drivability then will take it to the dyno. Hopefully before September 1

Transmission is in and working as it should . Converter drives good but looser cruising than the PTC did.
Cruising temp on transmission is around 175 , goes up to 180 when I get in it hard but cools back down.
Engine coolant temp is running on the hot side. Idles at 185 until I go drive ,then goes 201. After a while its creeping up to 215 at 60 mph and 225 at 70 after a 5 mile at 70 pace.
I have to install the electric water pump them then I'll work with getting temp right if that dont fix it. Maybe a big aluminum radiator is next.

1) flushed the system.
2) less than 50/50 mix
3) water wetter
4) 180 thermostat
Those changes were worth about 7-10 degrees
Then I changed out my trans cooler to a better one. That helped a lot with the creeping temps at cruising speeds. Then I was having problems still with temps creeping up in stop and go and low speeds. The convertor slippage was the culprit I suspect. I put a 7” fan on my trans cooler and that stopped that and my temps don’t creep anymore. I started out at a max of creeping to 217 and now I may see 205 on extreme situations but normally 190-200. I have a dual row aluminum radiator to go in it now because I’d rather have it around 180-190 if I can.

I had the same issue. I brought temps down by:
1) flushed the system.
2) less than 50/50 mix
3) water wetter
4) 180 thermostat

I have 2 bottles of water wetter to put in when I do water pump as well. For now I changed the stoich in my tune to 14.12 as commanded air fuel for cruising and that helped a lot. E10 gas should be set there anyway so I figured I'd see what it done. It cruised after at 198 and got up to 207 on a hard pass so its helped.

I have it cruising at 201 for now. I was able to make some good hits on it, this fti converter is a bad bitch 😁. Flashed to 5300, and in top of 2nd gear it has 5.5% slip .
It falls about 1200 to 1400 on the 2-3 shift from what I've seen so far but I guess to make it drive good non lock up, it has to.
Which is fine ,it will hold a 100 shot if that's all its falling

It was 7230 (if I remember correctly) @ 92 mph
Locked up figures would be 4.10 gear x 92mph x336 = 126,739 x1.48 (2nd gear ratio in tra s)= 187,574.
÷ that by tire hieght 27.4" and locked up would have been 6846 rpm.
Add that plus 5.5% to get 7230

Ive always wondered how convertor slip is measured. Autos are not my skill set. Thanks for this.

Water pump and new radiator in. Still have to wire up the pump and fill with fluid and also change an ac line. Broke it trying to get the condenser lined up with radiator and lost all the oil and freon.
Had to leave to come to the nursing home with wife for her mother, hopefully get it finished this evening then change ac line.
Slow process But im getting there

Not sure why but it's still getting up to 219.degrees. I've bleed the system several times today, water pump works great but still not cooling.
I drilled and tapped the front and back of the heads and run 4an lines from rear,tie in to front then to the radiator
Has a nice stream from steam ports to radiator, might move those into 2 separate lines returning into upper radiator hose instead. Back 2 y into a single 6an into the hose and front 2 doing same thing.
Not sure what else to try
