a couple of months ago. guy i got it from was the one doing my engine, body and paintwork, said it was a 400 WU block, trusting him, i did not verify until it was rebuilt and installed.
BIG MISTAKE.
im gonna contact him and see how we can sort this out. I dont have the funds to do another rebuild and theres no 400 lying around, ill prolly just ask him for my money back.
