The engine mount frame brackets from a '73-'87 C20 or C30 will fit the early frames better than the C10 brackets. These will also move the engine forward some. Another option is to use '68-'71 big block engine mounts and the frame brackets. On my '66 Suburban I fabricated my own engine mount brackets and used '73-'87 headers. Also my Suburban isn't lowered other than the extra weight of the big block. I recommend running a short water pump, especially with a big block.
