Here's why they recommended that converter. You need it. That camshaft has 248.5* of duration @.050", plus it's ground on 108* lobe centers. It's a BIG hydraulic camshaft, even for a big block. If you got the valvetrain and head work for it, it'll keep pullin to 7K. Also, what rear gear? Either I missed it, or you didn't post it. I would recommend a 4.10 with a 27" tall tire max. Any taller and I'd say 4.30. I say run what you have since it's already together. It'll run good......absolutely true though, is what Meep-Meep said. You can do it with less camshaft.........but then you need less stall, less gear, you get the picture. You'd need to change the whole package. The package is good, long as you don't mind the deep gears it will NEED.
