World products might make a good block but my new 427 engine from them was a piece of crap. And Bill Mitchell's customer service was too.
I am not an engine builder so I paid big bucks to get a tunkey aluminum head engine from Mitchell. It smoked heavily from the start, fouling plugs with in a 100 miles. I was told by Mitchell that the rings needed to seat. I ran the car and the smoking did not stop. His customer service told me that I may have the wrong valve seals. Sure enough every cheap umbrella seal had been pulled off. I installed new seals but this did not cure the problem.
I spent alot of time trying to get them to take care of the problem. I had even sent them a video of the smoking from the first few days of it running. I had changed the oil pan to a road race pan and they refused to honor the "Warranty" because of this. They claim a notice was sent with the engine informing that any changes would void the warranty. IT was not!
I finally broke down and tore the engine down. EVERY ring was gapped to 58 thousand or MORE! I informed Bill directly of this and he still wouldn't take care of the problem. Not even pay for the parts! I told Bill that at every opportunity I would tell people of his lousy engines and service. $9000 for that.
