Got the subframe together and ready for the big block. It is a 468 that will eventually get a pro charger, that will be matched up to a 4L80E. We had to use a TH400 trans mount and move it back in the subframe about 4" to fit the 4L80E.
The subframe is under the car, and back on the ground finally! The trans seems to fit in the tunnel with no problem.... only the cooling lines being tight.
