hard to start

i have a 400 sbc in my 87 montecarlo.
sometimes when the engine is warm (after heavier than usual driving) the car is hard to start, it will crank over VERY slowly about four to five times and then start no problem.
I have changed the battery, the starter, added two more #6 ground wires,
changed the altenator and the belt, the headers are ceramic so there is very little heat going to the starter but I installed a heat shield anyway, i even went as far to get a new chip for the computer from jetchips as i thought it was the timing, but still it is hard to start, can anybody help me, it has never let me down but i know it is only a matter of time!!!

What you might want to check are the springs and weights in the distributor and how freely they return when the engine is shut down. The whole thing sounds like too much timing while the engine is cranking.

When you say that you changed the starter, was that a new starter or just another that you had? I had a similar problem and swapped out the starter for another I had. The problem continued. It wasn't until I put in a new/remanufactured starter that I resolved the problem.

I have to agree with engineczar, it sounds like to much advanced timing. If you have a vacuum advance it could be sticking also.

Have your starting system load tested most auto parts store will do this,it is possible that it is a timing advance problem but i doubt it?

The starter system should be checked for voltage drop.
