Rotor pointed @cylinder 2?

Ok so I bought this chevy 350 from a friend years ago and he had kept some parts off of it for his new 350 one of which was a balancer so i bought a new harmonic balancer and put it on only to find out my marks on balancer were off.i then brought piston #1 up to tdc verifying it was on compression stroke and drew new 0 mark.then dropped in the distributer and it started up and all was good.well over the weekend I wanted to adjust the timing and noticed that when at tdc that my rotor is pointed to cylinder 2.i pulled dizzy up and pointed to #1 and dropped back in but would not start unless advanced all the way until vac can hits intake and then it still needs to go more.i double checked everything I can think of except cam timing.it has a gear drive in it and I did have the cover off when I first got the engine but could swear I had rotor towards cylinder 1 but maybe not.does this sound like cam timing could be off?it did run good a couple years ago when it was on the road.oh yeah all of my wires on cap are correct firing order and go to the right cylinders.any help would be appreciated.thanks

Re: Rotor pointed @cylinder 2?

The dist. would have be turned way far if it pointed to #2.
You have drop in dist. earlier cause the gears being cut at an angle effectively turn the dist. as its lowered in.

It should point to #1 when correctly installed.

Re: Rotor pointed @cylinder 2?

Yeah I had it running fine and then decided I wanted to time it better so I pulled plugs and rotated crank with finger over cylinder 1 and heard and felt air as piston was coming up so I thought for sure I was on comp stroke.i then drew a small mark at 0 then rotated it in opposite direction until tdc and drew another mark then drew final mark in between the two.so then I rotated it again cw until tdc on comp stroke.thats when I noticed rotor was at #2 so I pulled dist and dropped it in so it was at number 1.then tried to start and back fired through carb so I pulled it and dropped it in a little past #1more towards water pump and got it started with dist all the way ccw but needed to go more.it just doesn't make sense.maybe I wasn't on comp stroke.ill try to work on it a bit more today and see what happens.

Re: Rotor pointed @cylinder 2?

If the distributor won't drop in all the way due to the oil pump shaft not lining up with the pin inside the distributor gear you can take a very long flat blade screwdriver and turn the pump shaft a few degrees in the direction you need to go to aid in getting everything to come together without cranking the engine to align things.

#2 on the engine or #2 on the dist cap?

Drivers side is 1 3 5 7 F to R

How did you find TDC with the heads on? You need to be way more accurate than sticking your finger in the spark plug hole.

Re: Rotor pointed @cylinder 2?

Rotor was pointing towards cylinder 2.dont know what happened or if I just wasn't on comp stroke but I rotated engine with valve cover off and waited until piston came up on comp stroke and was on tdc on balancer where I had previously marked tdc and the dropped dizzy in and it seemed it would only go in and point at #3 or just past 1 so I left it just past 1 and it started right up.now to get the timing correct.thanks for the input.kinda feel like I jumped the gun and posted asking for help lol.ill make sure to search for more info next time.thanks again.

Re: Rotor pointed @cylinder 2?

Remember, number 1 is where you make it in the distributor. Don't worry about where the rotor is pointing in relation to cylinders. Follow your marks, make sure you are on the right stroke, and place the distributor in. Then where it is at, is number 1. You can re-stab the distributor to get it where you want it to be if you had the rotor turned in such a manner that it won't allow you to make adjustments due to where the vacuum advance is. If it doesn't fire up almost immediately, (with minor adjustments to dizzy), you are on the wrong stroke more commonly known as being 180 degrees out. Pull it, rotate the engine one turn, re-stab.
