What type of 428 / rebuild questions
By Royce P - 04/19/2004 9:20:10 AM; IP 152.163.253.1
Your 428 is either a service block or a punched out 390. Ford quit building 428's in 1970 for production use. Some replacement engines and marine / irrigation 428's were made using the D2 block you mentioned in the original post.

The Silvolite pistons give different compression depending on the volume of your combustion chamber and how far the engine has been bored. There are few options for cast pistons available off the shelf for a 428 because demand is low. You might have a more ideal piston made by one of the custom piston manufacturers from a forged blank. I have used Ross, JE and Wiseco pistons with great success but there are a half dozen other manufacturers too.

Another option would be a set of used pistons. Companies like DSC, Perogie, Carl's Ford Parts, Precision Oil Pumps and FPP have good usable sets available. This is probably the best option for your application, you can get a high quality forged piston at very low cost in this manner by shopping around. I would not buy a used set from just anyone and they need to be thoroughly cleaned and inspected before use of course.
