I yanked the original 400 SBC out of my '77 k20 and slid a 454 in with no problems at all. Used the same mounts and everything. Did have 1 small issue with oilpan clearance on the front xmember (maybe not the right way to fix the problem but) I just wiggled a prybar tip between the two a little at a time till they cleared each other and have been running it for a year now with no problems.
