It's just like any other motor. Like moparkid said, yougotta have everything to match the camshaft. Higher compression, bigger valves, good head work includin port work, loose converter with an auto and deeper than stock gearing. The smaller the cubed motor, the more easily it is over cammed. In other words, a .240@ .050" camshaft will be much more radical in a slant than in a V8. moparkid has got you on the right track. BTW moparkid, that's a wicked soundin slant you got.
