torque converter for 1982 spirit with iron duke and 904

[cocline71]

I am having a hard time finding the right torque converter for my 1982 spirit with the 151 engine.  I need a three pad 27 spline non-lockup converter that goes from 904 tranny to gm flywheel.  Can anyone help me out here?  I have searched all over the internet without any success.  I am considering putting a chevy th350 on instead.  Does anyone know if the fly whel will work for the th350 or what size I would need if I decide to go this way?  Also, should it be a th350 chevy bolt pattern or BOP?
Thanks, Colby Cline

the 151 has a SBC bolt pattern, lots of engines you can bolt right up to your 904, or going the other way the 151 can bolt to a th350 as well as far as the bellhousing goes

Not sure about the flywheel / TC it may be an odd peice to mate a chevy to a chrysler, hmmm have to think about that one....

My Spirit had a 151 mated to an SR4, so its a chevy to ford bell

You may have the wrong flex plate. Torque Command transmissions were four pad. That sounds like it's a GM transmission flex plate.

Changing the flex plate is tons easier than trying to mount a foreign transmission. Just pick up the correct one at the parts store. Tell them an '82 CJ 5 if they don't believe you.

It may or may not work with a 350, but a 200r4 would be a better choice if you're going to the effort to put a new transmission behind a 151. The 350 could have one of two different spacings on the torque converter, so you have a chance you'll get the right one.

The 151 in AMC applications is a Chevy SBC v8 pattern, the 151 for the same year GM 151 is a metric v6 pattern.

thanks Ben for the clarification

The folks on this forum will find you the right answer

Not to cause further confusion but the AMC I4 used the GM v6 pattern as well, go figure

I am sure that the flywheel is correct.  The torque converter bolts to it and fits the transmission correctly.  I am thinking that having the torque converter rebuilt might be my best option.  It's amazing how many different parts AMC used on vehicles.
