If your L79 was rebuilt with the stock spec L79 camshaft, you'll find it works very well with an automatic or standard transmissions. Not too radical an overlap, draws good vacuum so power brakes function correctly, won't load up at idle like more radical cams do. It actually works very well in 350's, much better than the stock 300 horse cams. I love the idle quality, plus the power.
Don't get me wrong - my 302 solid lifter is still my favorite, but the L79 hydraulic runs a good second place.
