Another tdv6 crank

Hey all, can anyone tell me if the tdv6 3.0 crank fits the 2.7? Mines spun and currently rebuilding it. Unfortunately it had a rebuild 18 months ago at £3600 but after me stripping it down it was clearly micky mouse and the gang who done it. My crank is salvageable but only at. 75 oversize and i never go further than. 50. So looking for cranks but the 3.0 seams to be cheaper? Alternatively anyone fitted a 3.0 twin engine in a 2. 7s place?

Are the block journals and caps still in spec size wise ? I would have thought if shells have spun twice there could be an issue?
Can’t answer your question with conviction, someone will be along shortly I expect
