OK guys i have a 1988 302 from a auto crown v going in my 1966 coupe. I have a toploader 28spline trans. The 302 is auto so i do not have a fly wheel but the 302 changed from a 5 bolt 289 and then changed to 6 after 65. Now i am using an 1988 302 with different bolt crank pully with a transmission setup for a 3bolt. Also iin 81 and after they changed to a 50oz imbalancer on thier flywheel. I am a little lost if anyone can help me out that has been down this road before.
