The GM #143 camshaft easily qualifies as one of mankind's greatest mechanical achievements. My '55 chevy runs mid 11's with it but you'd never know by the mild mannered idle. I've been tempted to change it out for something more wild but after a blast through the gears, I always decide to leave it alone. Anyway, it's a fantastic camshaft for stock stall converters and great for four speeds as well. An L-88 camshaft with a four speed or a stock converter on the street is really not that pleasant to drive due to the lack of torque down low with all that duration.
