Can't Start my 66 Mustang when engine Hot, 347 stroker. Can anyone help Please

[ziggy]

Hi Everyone. I have a problem with my mustang 66. I have just had a new engine rebuild with a 347 stroker and all the good bits put in it. It starts perfectly every time when it is cool, however when i take it on a good run on a warmish day it will not start until it cools down. The starter just clicks and that is it. It will not crank at all. It does have headers which are quite close to the started motor. We feel that the starter motor is getting too hot and hence the problem is occurring. Has anyone experienced this problem and if they have do they have any solutions. Thank You.

Touche`, get some heat wrap/shield starter from the exhaust headers!

Had a similar prob with my 302.
Would start every time when cold but not when it was warm.
A new battery fixed it.
Is ur battery OK ?

I overcame this on my last Clevo with an alloy heat shield I made up to create a barrier between the starter and solenoid and the extractors. Fixed it great

You will also need a heavier cable from battery to starter if you still have the orig one.
I had same prob and i put a heavier gauge cable on and routed it away from pipes, no problems since.

Had the same problem on the 390; start fine when cold but did not like it when hot.  Bigger cable from the battery to starter solinoid and a few miles (around 100 I think) to run her in and she is now fine- starts no problem even on the really hot days.
