If I was putting a big block in a A-body I would get a quick time bell and Hydraulic system from Brewers. That is what Steve is doing for the valiant. No dealing with linkage and the rest of the hard to find parts. If its a factory Big block car keep it factory. Or if your installing a big block for admiration
But If your using a built engine with headers and you want safety with performance and ease of installation use this. factory aluminum bells don't like big horse power with sticky tires
