Re: Big Block Perches
I would use either the '68-'71 factory big block brackets and mounts, or a set of brackets and mounts from a '73-'87 C20 or C30. I have no idea about fitment of your headers., Are they supposed to be for a '63-'72 truck with a big block? On my Suburban I just used Hedman headers for a '73-'87. Of course they are long tubes. When installing a big block in the '63-'67 trucks, it is advantageous to trim the top flange of the frame as was done '68+ to clear the manifolds/headers.
