We've been trying for 6 years to get our restored 1953 3100 216 straightened out. Last weekend, we put a new correct cylinder head and rocker arm assembly on and got it running, however it seems to be misfiring. Here's more:


-Newer carb, all settings have been double checked. Gas filter is new as well.
-Fuel pump is pumping lots of gas to carb
-All points and rotor button are clean and gapped correctly.
-All rocker arm/valve clearances are to spec.
-Timing is correct.
-Coil is working and all wire connections are solid.
-Plugs are good and gapped correctly.
-Plug wires all have good connections
-Full compression on all 6 cylinders


What else is there? Our truck fires right up, but then gets to spitting and sputtering, no power on accell, only idles on 1/2 choke, and is running rich.

We've thrown up our hands because everything we know to do has been checked over and replaced/rechecked 20 times over.


Bad camshaft?
Timing marks wrong?
