318 swap gone wrong?!

Is the car in a heated space? or is the ambient temp at least 60>70 degrees?
Did you oil up the cylinders?
did you clean the Plugs?
and verify the firing order?
Did you do a compression test with oiled cylinders?
Did you block the choke open, and set the Fast idle up on the Second highest step?
Is the carb still pissing gas into the intake and cylinders?
Did you change the oil?
Is the battery fully charged?
Did you purge the gas-polluted oil out of the lifters by cranking?
Did you set the timing into the window of 8>18*


If you did all those things, but didn't bother to show your compression results, then I guess
1) it's time to check that the distributor rotor turns lock step, while cranking; and if it does,
2) then, just maybe it's time to check the cam timing.
