I'll bet the distributor is 180 degrees out? Did you watch an intake valve open and then close to make sure it was the compression stroke and not exhaust stroke? When you tested spark, were all 4 plugs out and touching the engine at the same time to see if they spark in firing order? Finally, are you absolutly sure 100% that the cam is timed right? When you pull the valve cover to watch the intake valve try to get a measurement of when the intake opens and closes in relation to the #1 piston. Good luck
