hot motor

I have a 1968 350 vette motor in a 1933 chevy. The car starts fine with an electric fuel pump and pump the accel twice. My problem is when I stop after running it for 3 to 4 miles and stop it, it does not want start back up. I thought the battery was weak put a new one in and did not help. When I fire it up its like a vapor lock. Could the timing be off. It is a double pumper Holley

Sounds more like you have 'heat soak' of the starter/solenoid. Do you have a heat shield over the solenoid? headers close to starter? Good grounding? ground wire from frame to body to engine?

You could go for putting a Ford solenoid on the side skirt of the fender like Madd enterprises does. or this one:

Note. 68 Corvettes were a 327, not a 350.

Wont crank. turns over fast but wont fire. Not being specific. Please be verbose in your problem . No mind readers here.

16+ initial timing will give you hot start crank problems. Most driven vehicles that are cammed like 20 initial, but will crank slow when hot. Fix is a starter retard device, or vacuum advance added from manifold source at idle to compensate.
