I have a 69 Chevelle with a 74 to 78 350, not sure exactly. I just replaced the timing chain and got everything lined up, it's getting spark and gas maybe too much gas. It still won't start, I'm at a loss. The plugs, distributor cap and rotor are all new. It turns over just fine. I'm looking for some ideas. It's possible the timing is still off but I don't think it's that far off.

 

run through all the timing set up.pull ! plug and roll it over to the compression stroke on number 1 cylinder and see what cylinder it is pointed at on the distributer you may be 180 degree's out ,or a couple teeth on the distrubuter gear .when you reinstalled the distributer assuming th timing gears are lined up .
