I agree with PKRWUD. Check the cables. High resistance connections will drop voltage and the speed of the starter is proportional to voltage. Lower voltage= lower cranking speed.

Check those block grounds closely. especially the one on the timing cover. Add another ground cable if in doubt.

There is another possibility if you changed your cam. A large duration cam will require less starting fuel. Big duration draws less vacuum during start. Less vacuum means less airflow. Less airflow means less fuel required to ignite. The stock computer is preset on start fuel for the stock cam and 19# injectors. To test this simply press on the gas pedal while cranking to see if it will start faster.
