Hi my name is Randy with Engines Limited. I have been in the numbers matching business for 35 years. I can help you sell your block. We have a stamp rental that will put the correct style and shape numbers on your block. My stamps have passed Bloomington Gold and NCRS judging. We also offer a full length broaching service, it makes the deck look like a factory finish. We use the Ohio Broaching machine, check us out on the web engineslimiteddotcom. Thank you, Randy.
