Exclamation Crank no start

Hi this is my fist post. I have a 1986 f150 351w carb. I have just put in a new intake manifold and valve covers in it. After taking out smog pump and putting new radiator in it I have a crank no start. It is getting gas. I am thinking it is spark or I did not install the distributor in same spot? I did put new plugs and wires. It was running fine before this was just leaking oil. Any help woud be great thank you.

Double check what you did. As I remember the firing order is different for the 351 compared to a 302.

I had an 86 302 F150 for a while and it had a weak ignition module. I think the ignition modules fail because they are right behing the radiator and get very hot.

Have you TESTED for spark?

Firing order and distributor position, note where the cap clips are:

Thank you for the help. I got it running. It is smoking out of driver side valve cover. Any ideas?
