did you ever get your car running right?

Did you ever get your car running right. I have a 1971 mach 1 w/351c 4v and the car dies when I put it in gear. Have tried everything i can think of. Any help would be appreciated.

I have a set of 1971 351 Cleveland heads with intake. They have round chambers, not D shaped.. does that automatically make them cobra jet or is there other cleveland heads from that year with open chambers? if there is, how do i determine which ones they are? they are reworked, and if they are cobra jet heads how much are they worth with intake?

To properly set the timing on a Cleveland it is roughly the same as any other small block from ford.
Disconnect the vacuum advance and plug it so it doesn't leak.
Start the engine and run it at 3000 rpm.
Set the timing to 36 - 38 degrees (use a timing light with a built-in advance)
Return the engine to idle an check the timing - that is the maximum timing you can safely set at idle unless you recurve the distributor.
Reconnect the vacuum advance.
