BRB engine replace for a BKD or a BKC

[DanG]

I've blown my BRB engine when I changed the oil without cleaning out the pickup pipe. Gutted is not the word it purred like a kitten before. My mate has x2 engines a BKD and a BKC which is easier to fit in its place and why please and cheers. Jus to add its mostly if eithers engine block is the same? I'm not really bothered about any auxiliary not fitting I can get that out of the doner car
