Does a CU (T25) engine easily fit a 73 bay? I have the option to buy a cheap one. Sent from my iPhone using Tapatalk
All type 4 blocks are similar, Heads differ. Your CU engine will have square port heads, as long as you have the relevant fan housing, heat exchangers and tinware it will be fine
No, but it can be made to fit, however, it will have had a hard time pushing a T25 along and if it’s cheap it’s unlikely to be worth buying.
