I have a 1988 2455 Ciera with a 5.7L OMC. I recently discovered the block is cracked on one of the cooling passages and it had been patched with JB Weld by the previous owner. I missed this on inspection before I bought it. Anyway...a friend has a 2655 Ciera with a 7.4L that he has offered to sell me. The hull is in bad shape but the engine and sterndrive are in great shape. I was wondering if the 7.4 will fit in my 2455 and if anyone has ever done this. His engine compartment looks a little larger but I have not measured it to know for sure.
