Too much? hell no. When I look at cams for stroker engines you really have to get into some larger grinds before you reach "too much". 258/260 is enough to have issues running power brakes, but it's far from too large.
This video is when I had 269/269 @ 50 bullet roller cam in there with 540 cubes. Was just seeing how low I could get it to idle (I don't run roller cam stuff that low just playing around).... man look at that fuel ratio idleing, not bad for a 1 barrel carb :glasses7:
