200-4R Behind a 340 and Reid Bellhousing Build

If you can't get your fingers between the converter and the trans (where the front pump is) it should be all the way "in". If you mate it to the engine and have around 3/16 gap between the convertor and the flex plate it should be completely engaged. If you mate it to the engine it will tell you for sure if it's engaged into the front pump or not because you'll either have the 3/16" or not. It can be less than 3/16" but should be much more than that.
