slow cranking when warm

have a Ford 302 in Model A streetrod. When the engine is cold it
cranks and starts fine. When the engine is warm it cranks slowly but eventually starts. Battery/starter are new. Voltage at Starter relay dips during cranking more when warm. 8-9 volts.

appreciate any help..

voltage drop

what is the voltage at the starter when it is cold?? what kinda starter do you have , did you have a dfferent starter in there b 4 with the same results. also I would start to check and see where the voltage is doing all the dropping and either clean or replace different parts.
start at the battery when warm and check for a voktage drop at the conector then at both sides of the relay and then again at the starter and see what your different results are you have way to much drop. also maybe get the battery tested if the drop is right at the battery.

Sounds like a bad starter to me, new does't mean it's good.

If you have your headers running close to the starter, which I imagine you do, then you need to get a starter heat sheild. They can usually be had cheap, and are easy to install, and should fix that heat soak problem of yours.

Heat, is an electrical components worst enemy.
