Got the parts back from balancing and started putting the 521 together. Never built a BBF stroker before. With the 4.300 crank there are no clearance issue at all. I was kind of amazed by that. I was expecting things to be close. I will start a post in the Project Builds as I get further along.
None planned right now. I want to get the motor and TKO 600 in and functioning first. I'm putting FiTech fuel injection also. So once all that is up and running then I'll go from there.
