Converter to Flexplate Torque Spec?

Just a quick question. I have a 454 and a TH400. I need to know the torque spec for bolting the converter to the flexplate.

Right now there is a gap between the converter and flexplate. Are there spacers or shims i use or just pull them together and bolt it up?

Careful, there matey!!!!! The convertor should pull right up to the flexplate with minimum force. Don't use the bolts to pull them together and you shouldn't have to use any spacers or shims. Be absolutely sure that you have the convertor totally seated into the tranny (it should turn relatively easily after 'clunking' into place) and then, when the tranny is installed, the convertor should pull (without to much effort) back forward far enough to reach the flexplate. If there is ANY need to crank down the bolts to pull them together, you need to watch carefully as somethin' ain't right.

No it spins very easily and i can pull them together with ease.

LoL I usually just tighten up my bolts as well but when they are bolts that are "in motion" or have some type of critical duty other than holding two pieces together, i try to use the proper torque specs.

Plus i like to use my expensive torque wrench every now and then...
