Ok , I can start my truck and rev engine to 3500 rpm ,It sounds good but when I put it in gear it wants to die. If i take my foot off pedal it will die. I did however get it to drive. It would not go over 5 mph and rpms would not increase.maybe 1000. Any ideas. I could floor my pedal and thats all I get. Then when I put it back in park it wont really rev up like at first. Thank you. Later when it cools down it seems to start up and rev fine. with same . actually i just started it up and its acting like results if i put it in gear. New carb ,hei, fuel pump. I have been having a misfire in my system and now this is happening . thanks.

Now it will not start again. It seems whenever I have reset hei on tdc. It will fire right up . Then later I get nothing. Cranks turns over fine kinda starts for a second and dies.

Are you setting the timing on 0 with no initial advance? Is your vacuum advance disconnected when you set your timing? I ask because it sound like possibly retarded timing.

If everything else checks out you might suspect Timing chain/gears may have skipped 1 or more teeth due to wear. Pull the timing chain cover to check.

any chance your hei is not getting 12 volts constant voltage or have you checked fuel pressure from lines mine had restriction in fuel line and also after start up volts to hei went from 12 volts to 9 volts constant had to hook up a 12 volt power wire to straight 12 volt power

If that is a brand new, aftermarket HEI, I recommend disassembling and soldering every connector. The factory crimps are done poorly, and will sometimes make contact, and sometimes not depending on which way the wind is blowing.
