I wouldn’t worry about how much power can be made but focus on everything else afterwards. On the engine build, I would yield at 9.0-1. A tad more is possible but the octane required may start to fall short if the cam isn’t big enough duration wise. This is an exercise of caution. Then select the cam. While the manufacturers list an rpm they operate in, it is a general one with the bigger engines in mind. So select the one down from the most performance oriented grind that works with your converter and gear ratio.
On the exhaust, duals with an H or X pipe will top it off just perfectly 2-1/2 max size pipe. And that is plenty large!
Which model is your transmission, rear end size, gear ratio and tire size?
