I think I blew the motor SR redtop

So lemme give you a little history on my recent tune.

I just installed 370cc injectors from 550s that were in my car. I've been driving around on them for about one week with no issues.

I took the car out for a spirited drive with no issues. When I went back out to start the car, it wouldn't start. Cranked over fine but still no start. I gave it some throttle and it started up but I had to force it. I opened the hood and I had what sounded like and looked like a misfire.

Because of the swap of the injectors, I went back to the injectors and did a injector balance test to see if the problem changed when I disconnected them. I disconnected #2 and the engine smoothed out and there was no issues. I plugged it back in and the engine sounded bad again. I drove my g/f to work and i was getting backfires once i got off the throttle. The miss was getting worse.

I drove it over my friends so we could troubleshoot. Once it sat for a while and we tried to figure it out I started it again but this time a terrible vibration from the engine all the way home. The oil smells like fuel and i'm really hoping its not bearings or cylinder walls.

Please please someone shed some bright light on me?!
