Well ive been working on my project fox for months and its finally come time to start it and Ive been having trouble. Im getting spark from the msd and fuel to the carb. It turns over fine but wont start. I have the motor at top dead center on piston one and checked to see that both valves were closed on that stroke. The dizzy is perfect with cylinder one plug lined up with the rotor. The troubling part is that even after all this the motor will still not start.
Here are some things ive been thinking:

When i turn the motor over with starting fluid into the carb, the fumes of the burned fuel comes back out of the carb. It seems like the intake valve is opening on the exhaust stroke and pushing the fumes back out of the intake. I was wondering if this could be a result of the cam being upside down or 180 out.

The block is a 302 out of an 89 town car. I was wondering what the firing order should be for this setup.

Please this has really been bothering me and I was just wondering if it is in fact possible for the cam to be opening the wrong valves at the wrong time. If this is the case what would i need to do to fix it?

If you haven't changed the cam the firing order should be 13726548.1-4 on passenger side 5-8 on driver.

is that an h.o. motor. if not the firing order could be 1-5-4-2-6-3-7-8. i was just thinking that it might not be an h.o. motor being its out of a towncar.
