Stop in for a cup of coffee

Can be done, but it's not drop-in.. Different trans, maybe oil pan, all new accessory brackets.. Pretty spendy..
Kind of an all or nothing sort of thing.
I put a 400 into a ‘59 regent,it was a 5 week project. Had a donor vehicle,which made it do-able. Motor, transmission and rear end from a 70’s pickup. i should have kept it for myself.
