I am sorry I did not answer back sooner (my computer blew a head gasket) Its really a simple swap -- the L-shaped brackets that bolt to the original 235 block will be re-used.The pass side L-shaped brkt. will bolt to the 250 block with two bolts. Then you need to make a 1/4" plate the picks up the three holes on the drivers side. A spacer will have to be made for the top hole and the plate bolted to the block with proper length bolts. I used a power-glide so the rear trans mounting will be the same for 350 turbo's and some standards(meausre yours).The trans mount in my case fell right in the center of the org. cross member. drill two 7/16 holes inthe top of the crossmember and on the bottom side( it's a square shaped tube) cut a slot for socket access.Be sure to measure your combination's
length and do the trans. mount accordingly. Bolt the motor in place with the trans mount and the pass. mount/level the motor/then bolt the driver side L-shaped brkt in to the frame. It will fit snug against the 1/4" plate bolted to the 250 block. Now weld the two together. You want to use the shortest water pump you can(I think 67 or 68 nova). the radiator will have to be spaced forward about 2" to 2 1/2" depending on the pump length. Then the upper hood structure will have to be trimed to clear the radaitor.
If your using a turbo you may have to trim the frt. of the crossmember for trans service--hope this helps--paulweldit
