got mine from FPS, I herd Fordstrokers is really good, Keithkrat I herd is superb. if anything i think it would be better to go to a local machine shop and having them do it. in case anything you can take it back instead of shipping the motor back n fourth.
but if you do go for an out of state shop
ask everything, even if its the most dumb question in the world they should answer it.
I had a nightmare with a shop in LA in the end he went out of business and took tons of ppls money including mine, finally i found him working at a company and I garnished his wages. he still owes me, but i can easily find him.
