I have seen some of the Glidden stuff floating around over the years. They were low 9 high 8 second cars with lenco 4 speeds. They'd be way quicker and faster today just due to 5 speeds and better clutches.
That said, the OP needs at the minimum a well prepped set of W-2 heads or better. And some kind of aftermarket block. There are still some X blocks floating around. R blocks are out there. You will need an R block with standard deck height for that stroke.
