You will need push rods, oil drain back lines along with the b1 stuff IE intake, rocker arms, valley pan ect You might find your distributor wont fit also. Joe Without Data, you’re just another guy with an opinion.

I updated to a nitrous piston so they may be for sale. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

The motor is just about complete so I guess at this point hind sight is 20 / 20
