351 Windsor hard to start when hot.
I have a '77 T'Bird with a 351 Windsor engine. I just had about $800.00 worth of work to it. New radiator, valve cover gaskets, etc. Even before I had the work done, I've noticed that after the car has been driven, and the temp guage is in the normal range, it is hard to start after sitting for about 15 minutes or more. After the engine cools, the car starts without any problems.
I've thought about the automatic choke, vapor lock (car does not stall while being driven), and fuel pump. Which of these do you think is more likely? BTW, the engine still has excellent compression. 40k on rebuild.
