starter problem

i have a basicly stock 429 with headers and some other go fun parts but my problem is it starts great when cold but take for a ride and it gets warm the thing barely turns over and by warm i mean anything above 150 on the temp guage i put in a biger battery and tryed a different stock starter and same thing i am thinking that maybe the starter is getting to hot with the header about 1/2 inch from the starter looking at the mini starter from dbelectric and was thinking this may help but what do you think is ther something i may be missing why it does this

check all your cables over and the ends.also make sure the ground is on the engine block from the battery and a ground to the body from the engine.

Also try some head wrap on the starter

i am grounded to the block from battery then to frame replaced all cables that looked bad i will try heat shield for starter see if that helps

Ignition timing ?

i am going to play with that a bit more i just put a new cam in and it did this before new cam and i have not cheacked timing yet still not sure what the best timing would be i just set it to run and break in the cam

Mine does the samething,BUT it's ME adjusting the timing advanced to get quicker et. when i do this it will start cold but it struggles and a bear when it's warmed up. Hope this helps

the only starter I us is a Tilton super starter....

Sounds like heat soak. I'd try a heat shield and wrap the header tube where it comes close to the starter. Heat reduces the magnetic field which reduces how much torque the starter can generate. If the heat shield and header wrap don't do it then the late model starter like you mentioned would be a good idea provided the transmission is an automatic.

Of course you do need to make sure your timing is not too advanced too...
