Starter problems
Anybody have a problem with their trucks not starting easy when they're hot? My 351W has been doing it even when my dad had it and it was running daily, but now once it gets hot it'll barely turn over at all. I've got a good battery but I'm going to replace the starter anyway just because it's got some age on it. I do have headers and think that the heat may be the problem, should I build a heat shield for it? Has anyone used the aftermarket high-torque starters? I looked at TCI and $150 is a little high for a starter but not bad if it makes a difference. Anybody used one? Is there a better solution? Thanks.

Heat from the headers will be a problem. Also if the timing is a little too far advanced it will cause the hot start problem too. If you have the stock ignition, it has a start timing retard function to help this problem if it's hooked up and working.

I just had the same problem. It was the starter. If you have a voltmeter and know how to use it, then measure the voltage drop between the various connections while the engine is being cranked and the ignition is disabled. The best way is to disconnect the BIG wire from the starter and use a head light as a dummy load in its place, so you don't burn something up, then jump the starter relay to keep the starter circuit energised. While the light is on you can take your time and find every poor connection in the system. You will be surprised what is waisting your cranking power.

After measuring the voltage drop I made all new cables and changed the starter relay. Every thing I measured was a little bit bad. Now my engine cranks over very fast. Just because something is bolted to something else dosn't mean it's electicaly connected. I even had a poor connection between the starter and the engine block?
