Vette is alive...but
I got my new crate motor fired up today and everything in that regard is great. However, while I was at it I changed the torque converter to one with a little higher stall. I put fluid in it before install and have added while new motor is fired up, but, the transmission won't even think about engaging in any gear. Is front pump not engaged? Looking for ideas.

Plenty. I also put about 2 qts in the converter prior to install. I talked to a friend and he said the front pump might not be engaged. I'm already up under the car but can't seem to get it engaged any further than it was.

Did you drain the tranny or just pull the torque converter and dump it?
I think you're still just low on fluid.
If the torque is bolted up to the flywheel and the bell is bolted to the block, the front pump has to be engaged.
Try filling it more while it's running. Have someone sit in the car and move the shifter back and forth from drive, to neutral, to reverse, to neutral, to drive until it starts to fill and shift.

I've already put like 8 qts in and it's showing high. I'm not sure how much the converter would eat. Fluid was my first guess and I made the extra trip to the parts store. I unbolted the converter but can't seem to move it any further than it was on the shaft. This thing is killing me!!

Should have said this I suppose. Didn't pull the trans, just the converter and put on a new one.

Someone else already said if the converter is not all the way engaged you're not going to be able to get the block and tranny to bolt up. When I dropped in my engine, I had to lift it back out because of that.

It will bolt up-get under there and spin and rotate and rock until you feel it go in-its a lot tuff doing it that way but it can be done-the ears on the front pump turns real easy so you'll have to get the converter to spin faster and thats not easy-be rough on it you cant hurt it- within reason--you might have to seperate engine and trans. a little to get pilot out of flexplate

If the converter is properly installed it should have been atleast half inch inside the tranny from the mating flange (motor/tranny bolt up). When you bolted up the converter, did you have to slide the converter to meet the flywheel? If not you may have jammed the converter into the pump.

friend of mine did this on his 70 charger and it killed the pumpas soon as he fired the car up.
i hope this did not happen to you.

Have you just shifted through the gears and it feels like it is not hooking up?
I just put a new 3200 in my car and when you drop it in gear it seems like the tranny is not hooking up, but if you raise the rpm's in gear the car works just fine.
Just food for thought
Hope you get it going soon

just an FYI the transmission holds 20 pints if it is dry and 5 pints with regular routine change. when i put my engine back in i also changed the pan on my trans and ended up puting about 2.5 gallons in before it would move the car like it was suppose to. just an FWIW

I don't see how you could bolt the engine and auto tranny together if the converter is not engaged to the pump. The converter would be 3/4" forward. The flex plate would contact the conveter and not allow the engine to bolt up to tranny. Maybe thing are different than my situation. I thought I had the converter installed correctly. Dropped the engine in the car but could not get the engine to slip into the dowels on the transmission. Lifted the engine out since I was not comfortable with the engine above my head hanging on a chain and hydralic jack designed and built in China. Pulled off the converter and put it back in. Noticed that it went in much further. After that the engine bolted up fine.
I dumped fluid into my converter prior to installing it. I had my pan off as well. I believe it took about about 6 more quarts to get it to the proper level after firing up the engine. I assume the poster bolted the converter to the flex plate.
