In a word, no.
I'd check the crankshaft to be sure there are no conversion bushings, bearings, bugs, rust, boogers, snaggers or anything else that might prevent the converter hub from entering the crankshaft register - for peace of mind I'd slide the converter in just for good measure. In my experience (and I just went out and measured every crank I have) the crankshaft register is around almost 1 13/16" (1.800 on my calipers) on the big blocks - some small blocks had a 1 1/2"-ish register. Torque converter snout should be a few thousandths under. As mentioned, slide the converter in just to confirm while everything is out and easy to get at.
You don't mention what Mopar it's going into, so there are a number of accessory issues that might crop up - if you know the year and body style of the car, and what engine and transmission it had originally I can supply more info.

What I recall is about how to put a 4-speed into a Mopar that originally came with an automatic. In this case the opposite is the goal: putting a PB TorqueFlite behind a 383 4-speed engine. Any special issues involved?
