A 455 Olds is getting pretty hard to come by these days. You could probably get a good buck for it and use the proceeds to buy another small or big block Chevy.

unless the '68 originally had a T400, you'll need to weld new cross member supports to frame side rails. the T400 driveshaft is also shorter.

About 20 years ago we shoehorned  an Olds 455/turbo 400 combo into a neighbour's 76 Nova Concours.  It can be done, but it wasn't easy and probably wasn't worth it in the end.  Todd is right, sell it and use the money to buy a Chevy set-up that will slip right in.

i don't know how many early 70's olds i transplanted their 455's into 67-72 gmc trucks. cars were cheap and transplants were easy.

455 Oldsies were one of my favourite transplants too..
GM was always great as the holes for any B-O-P or Chevy engine mount stands and crossmembers were usually there on many cars already so robbing the conversion parts from a donor car was the easiest and cleanest way to go..
The later 70's trucks that used the Olds diesels made it easy for the transplants being they had the Olds mounting holes too..

If you look at your '68 and the extra holes are there already, look for a boneyard similar year B-Body Oldsie w/ the parts to make it all a factory fit..
