Yeah sort of, going to try 26 internals in 25 block so just a mockup/low cost rebuild as a test to make sure its going to work, pistons are the main thing I need at this stage I think I seen new OEM pistons were about 100-150ea so not far off just going forged but a bit more than I would like to spend considering its just a trial at this stage.
As for the oil pump I accidentally broke the housing.
