It will run with the cam off as many as 2 or more teeth depending on the cam specs. If you have the specs for the cam and a dial indicator you can pull a valve cover, setup the dial indicator and see if the #1 intake valve starts to move at the proper degree on the damper. It is fairly simple and a lot easier than tearing the front off. If it checks ok then you can eliminate it rather than guess and tear it apart for nothing.
As someone stated above a compressing test will possibly show cam timing issues as well. If you know the engine is healthy and the compression is below say 110 on all cylinders then most likely your valves are opening at the wrong time. The compression test and checking the valve opening should tell you the story on the cam timing.

woww I feel like an idiot. After alot of talking about how the engine works with my dad tonight i think i realized that the distributor is 180 out. After talking about how the piston comes up twice in a rotation on the exhaust and power stroke along with the number 6 cylinder i realized that they both are up at the timing mark but one is on the exhaust and one is on the power stroke. So since its too late to fire it tonite with worry of it backfiring and waking the neighbors I will have to wait till tomorrow to test my theory. But I am almost positive it is 180 out now.

On another note I did compression tests all around and all were around 120 except for one that was around 75 at best. Now I know that isnt good but this engine is just for the transition period untill I can yank the 350 from my old car and drop it in this one.

Ill post tomorrow again, hopefully saying she starts and sounds great!

Matt

Don't feel bad. It's the only way to learn. I remember when I was 16yrs old I rebuilt my first engine 69 Nova 350SB. I was trying to get it started. Man , it sounded like a cow with a bad case of indigestion, barfing/moaning out the front & rear. Ha!Ha! My dad opened the back door and shock his head then said it's 180* out of timing. Pull the Distributor and turn it 180*. As usual he was right.

aw well after being pumped about starting up the old engine today i lost spark at the plugs. I checked to see if the coil had spark and it did after I arced it to the firewall. When trying to do the same with a plug wire and spark plug I didnt get anything. I had a spare rotor and cap and put them on but still got nothing. Any ideas? the plug wires were on my old el camino that ran just fine when they were taken off.

Coil wire could at be bad. If you have spark at the coil and not at the plugs it can only be the wire the cap or the rotor.

Well i know the wire must be good because thats what we arced with. I also put a new rotor on. My question is could it be the breaker points? or could it be a wire in the distributor? I know there is one that goes from the negative on the coil to the points and im not sure what that does. Also, There are some wires that go around in the distributor. Could any of these not let it start?

If you have spark at the coil, unless something is drastically wrong or you have something not installed correctly you should have spark at the plugs. I think you should start over from the begining. MAKE SURE THE DISTRIBUTOR IS IN CORRECTLY. This is the most common problem. Its not hard to check but it is probably the most common no start problem. If the points were not opening you would not have spark at the coil. There is only one source for spark and either you have it or you dont, if you have it at the coil it should also be at the plugs.
You need to start over, take a methodical approach to getting the distributor in and checked. Check the firing order twice especially 5 and 7, they are real easy to mess up. You will get it running.

Good Luck
Chet
