Question TPI 350 Distributor installation question?

I have a TPI 350 from a 1988 Pontiac Firebird it was installed into a S-10 truck. During installation I broke the distributor and replaced it with a junk yard unit. I must not have installed it correctly because the motor will not idle or rev up without missing very badly. I know that #1 cylinder should be at TDC, but where should the rotor point? I must have the distributor gear and the cam gear meshed in the wrong spot. I looked at past posts and only found one that helped. I am asking for more specific information. Also the TPS, MAF, cap and rotor are all good. Thanks <img src="graemlins/evil.gif" border="0" alt="[evil]" />

#1 should be on tdc on compression stroke. rotor should be pointing at #1 plug wire. you have it running now, probably just needs timing adjusted. good luck!

To be more specific I want to know where #1 is as if you were looking at the face of a clock. The rotor is the hand of the clock and the firewall is 12 the radiator is 6. Can #1 be in any position or at a certian "hour". Hope this makes sence. Thanks

No. 1 should be at approximately the 5 o'clock position.

It doesen't really make any difference where no 1 is as long as the timing and firing order is correct

Today I tried to reinstall the distributor but was unsuccessful in getting it to run right. Now the motor will not even start! My friend told me over the phone that I am surely 180 degrees out. And that the motor compresses air on both the intake and exhaust stroke. So that was probably where I got mixed up. Who knew that the timing was such a hard thing to get right? Now I am going to try it again... Thanks for your help please keep the ideas coming.
