Fire59Rescue

I recently installed a reman 360 in a 1969 F250. In addition I rebuilt the carb, overhauled the distributor, etc, etc.

It now runs great, has great power, and looks good as well. The only issue is that on a hot soak (10-15 min) the engine cranks for a while before firing, and then sounds like its loaded up.

I have rechecked the float level, verified no fuel dripping from the metering assembly or idle ports, checked voltage at the coil, spark quality, etc, etc, etc.

After fooling around for a few days I found out this truck has always had this issue - possibly since new.

I don't recall ever having this issue in the past, and all of the obvious issues seem to be OK. Any older techs or Ford guys out there who might have seen this before? If so, any ideas?

BTW I am a professional tech - I feel pretty confident everything is as it should be, and if there is a solution it may require some type of modification/change.

Thanks in advance

My 71 390 did the same thing for a long time. I replaced the rubber line from the mech fuel pump to the carb with a steel line. It seemed to fix the problem. Probably keeps the fuel cooler. good luck
