One wire lock-up, 4 spd automatic w overdrive into A-body.
Third time was a charm. The torque converter fits perfectly! I bolted on the 318 neutral balanced flexplate/tone ring to my old 5.9 Magnum, dropped the torque converter all the way into the transmission and bolted the transmission to the engine. tMy 408 is internally balanced There was between just a touch more than 1/16" less than an 1/8" of room for the converter to pull forward as I tightened the bolts from the flex plate to the converter, which was spot on perfect distance according to the chevy manuals.
I am so relieved and happy that I didn't have to ship it back to be adjusted again. Now Precision has the exact specs to build both lock-up and non-lock-up converters for these Reid bell housings. If you are no into long trips and use your car more around town and at the strip, go with the non-lock-up style converter; as it has less mass to spin and will accelerate quicker.
Now, I just have to finish swapping the serpentine stuff and oil pan and pick-up on the new block, paint it all up and do some minor torsion crossmember modification along with some additional welding to strengthen the k-member and weld the torsion bar frame solidly to the floor like my US Cartool sub-frame connectors. I will also add some gusseting at the ends of the sub-frame connectors to the torsion bar cross member. I will have too make a rear trans mount too, but I already have a good idea for that from the Hotchkis build.
What a relief the torque converter fits, whew! :blob:
My only concern now is if the (blue) metal behind the tone ring's rectangular holes will affect the pulse and cause problems with the fuel injection due to not enough airgap behind it. Does anyone know about such things?
