basis pulley question

[busteed]

I removed the AC from my car and swapped out the 318 for a 360.  I am no longer using AC so, do I need to get a different crankshaft pulley (# of grooves)?  I am still running power steering.  I beleive it is a 3 groove currently.

You can leave your crank pulley as is without harming anything.  If you decide you don't like the look of the unused groove down there, then by all means find another one but it isn't doing anything bad with it on there now.
