Torque Converter Installation Question
Just want to get this right. I've never attempted this befoe.
I plan on removing the stock engine and torque converter from my '73 and replacing it with a 383 and new torque converter, starting tomorrow.
Which is the easiest, or safest, or best way handling the converter installation?
T.Q. bolted to flexplate, then install engine onto tanny shaft/case?
T.Q. fitted onto tranny shaft, then engine installed onto tranny case, bolting converter onto flexplate later?
At any rate, I plan on draining the tranny fluid in the beginning, and replacing the front case T.Q. seal.
Just asking for advice on this from those who have experience with it.
Thanks in advance,
Steve

TQ is installed into transmission, and you have to know that the notches on the hub have to fit the oil pump and it will slide back another 1/2-3/4 inch, this is a MUST DO, if that puppy is forward, the flex plate/crank will force it back into the trans oil pump, and break it.....so measure across bellhousing and look at the offset, and it better me much greater than any measure of the crank/flex as the TQ slides forward maybe 3/8" when it's bolted to the flexplate.....

In addition to the above, you are going to hear one clunk, and then push and rotate until you hear a second clunk as you feel it move a bit further. When fully seated you probably wont be able to fit your fingers between the converter and the front pump of the trans, but it will be close.

The info above is absolutely correct. One piece of advice - fill the converter with fluid before you install it on the front of the trans. Add fluid with the converter flat on the ground, 1 - 2 quarts until it comes out when you stand the converter up.

Thanks folks.
So, I understand the converter will mount onto the transmission shaft (with notches engaged to tranny's oil pump) and be supported by that tranny shaft and not damage the new front transmission case seal I just replaced.
Correct?
And BurgerKingBroiler, would it be 1 qt., 1.5 qts., or what, before it starts to outflow when stood on it's edge? Is there an exact amount? I guess it's just a way of hurrying up the filling process of the entire transmission, and not making too much of a mess, right?

I do not any benefit to putting fluid in the converter before hand. The transmission pump will immediately start filling the converter when the engine is started.There are no parts rubbing together like in an engine.

Just be sure the Higher Stall converter is going to work with your motor....I found out the hard way with my 375 HP 350, rebuild trans, shift kit. Punch it off the line and it falls on it face until 10 MPH and then hold on.
All is coming back apart and a 2700 Stall Converter is going in.
Gotta have smoke and not just a chirp.

I like to add some fluid to the converter too. It's a gentle maneuver to get it seated. Once I get it seated, I saw this trick of using a wrench to hold it in place while you get the unit in position.

Seriously, though, that's a VERY mild cam (204/214), I think a low 2K range converter would be fine. With a 383 and that cam, you'll have tons of torque down low. I'd probably run about a 2200.
