OK, is the firing order in the 1976 Service manual correct? I have checked the firing order 3 times and it is correct. I did not remove my distributor during the manifold swap, and I'm pretty sure it is not loose. All plug wires are tight.

Engine idles fine, a bit rough, but normal, but under any sort of accel or load or even revving in Park, I get constant backfire. WTF???

All I did was R&R the manifold. Is it possible I have a leak between the ports and the crossover ports? I wouldn't think so. Nothing else has been changed...
