Sounds to me like you may have broke a rod.

I had an 84 Z28. Got on it hard one day all of a sudden I felt a loss in power. Didn't think anything of it and drove the car for the next 3 months. I had no knocking at all. Finally went and had my 350 installed and pulled the 305 out and opened her up and saw that I did indeed have a broke rod. Broke right around the crank, hence the reason for no knock.
Im not calling you a lair but I find that very hard to believe, even if it broke at the crank, the next fuel/air mixture that came into that cylinder and inginted would have blown that rod/pistion but out the bottom and jamed up the crank.
You would know if you broke a rod.

this here is why I'm never spraying my car. I may put a blower on it but only after it has the proper prep work for it.

seems like it's easier to tame and adjust for a blower. Just add more fuel and make sure under boost it's running rich not lean.

I've heard too many stories like this of booms caused by N20

As the title states i was driving home just now and i sprayed the car in 2nd gear at 3700 to the end of 4th gear, around 5000 rpm in 4th gear i noticed the car wasnt really pulling any longer so i pulled over. the idle of the car now has a ticking noise which isnt that loud and when i get gooing from a dead stop or even when accelerating the car shutters like something is holding it back? ANY ideas and costs of the repair? it was only a 90 dry shot and my car is a 2000 gt with intake and exaust and it wasnt the first time spraying it
I would first check and make sure you didnt burn a plug, if thats ok, i would then do a compression check both wet and dry and see what you got there, so you will now if you burned a vlave, burned a hole in the top of the pistion etc.

Check the plugs, you may have burned one.

Yes you are calling me a liar. Why would I make that story up? It happened. I really don't care if you believe me or not. The rod was broke. I drove the car for about three months with what felt like a miss. Got my 350 put in and took the 305 apart and it was broke.

a guy i know drove a bronco for a few months with what he thought was a misfire. turns out one cylinder was as dead as you say, could either be a blown rod or it possibly was a hole in the piston.

with V8s problems with one cylinder aren't as obvious as theyw ould be with a smaller engine
