Good engine builder in South Jersey
I am using Jordan Machine Shop in Hainesport for my 340 machine work. The owner (Gil Jordan) is a one man band, so if you use him, don't expect a rush job.
He will do whatever level of work you want, from just a clean up honing to full bore rebuild. He has a 426 hemi (another customer's) in his shop along with my small block and has routinely built hemis for Joe Gerdleman. However he handles Chebbies and Ferds routinely.
Let me know if you want his contact info.
