Hello, hope someone out there can point me in the right direction. I'm building a big block Tmax 3.3 using a stock extended chassis, I have everything mounted using a Big Red .28, however, I m lost on a manifold to use that curve over the shock tower as the stock one for a big block. Do they make a Tmax big block manifold so I don't have to hack anything? Would the O.S .21tm manifold work on the big red?
