Not Running

okay i have a 1985 v6 camaro one day i took it around the block (tabs were expired needed to be driven) ran fantastic no problems. went to start it the next day and there was kind of a pop and the car hasn't started since. there is compression spark fuel all the neccessities for a running engine i am very confused...........any guesses? my dad suggests a sucked valve, i say i hope not cuz im too broke for that.
thanks

blown gasket mabey. I'm not sure. Dose it start?

Doesn't start...... turns over definitely wants to start though its getting too much or too little of something........ i dont know dude its a tough call

hmmm.... i'm not a chevy man, but I had a similar incident a few years ago....mine "jumped time" and then because i tried to start it out of time sent fuel to the catalytic converter and froze it up. I had to replace the converter and put it back in time and
( replaced the worn timing belt) in the process.
