Nice...…. :cheers:

For a 2nd method, instead of drawing a chord, dividing it and drawing perpendicular to the center, (too many chances for guessing, drawing, etc IMO) simply take a fabric tape and measure the distance between the 2 marks around the circumference. divide the distance in half and mark accordingly.

Remember, slow progress is still progress. I have to keep telling myself that.

JD, it's not unusual for harmonic balancer rings to migrate over time. 32 degrees might be the worst I've seen though.

Did I mention that my Daughter works for Sharpie? Keep misplacing those things; I need her to stay employed. :lol:

> 32 degrees

I've seen more than that.

Ford used at least five different timing pointer locations on the small block, with matching balancers. No telling what your aftermarket balancer was marked for.

Remark the balancer or make a new pointer, whichever is easiest. (those "timing tapes" for balancers are pretty handy, though)

Hey Chuck! Remember when I said:
Quote:
So then, measuring the arc around the balancer and measuring the mid-point of the chord of the circle and finding a line from center of balancer thru the chord at a right angle (Oh Emm Gee! He's doing geometry!!!) and thru the middle of the arc and I get a new TDC mark.
I kinda ran right on past that "measuring the arc" part. I did pretty much what you're saying, measuring from stop-point to stop-point around the perimeter of the balancer and finding the midpoint. I used a strip of paper because I couldn't find TWWTFM's cloth measuring tape, but same measurement. Marked that point first, then confirmed with the "center of the chord" method. You're right, it's much easier and more "Bubba-proof" than the geometric version.

Hey, JD. I'd love to take credit for the piston stop idea, but I'm not that smart. It was somebody else.

Cheers,

Oops! My mistake... :oops: It was Tim/Geek49203 that tossed out that little gem. Thanks for the correction... But it COULD have been you...

Thanks to Tim for reminding me of the technique.

JD, I must've missed that part. I'll just blame it on all that "Green" blinding my eyes. I'm sure it can't be me getting older.

"I took geometry in the year 19-mumble-mumble"
OK... I'll risk it... I last studied geometry in 1959... mumble... mumble... The year after I discovered F1...
[I hope this doesn't create a flood of 'mumble... mumble...' jokes...]
Best wishes for a speedy solution - for you... - is it too late for you to get back to the autox this year...?

So why did yours migrate so much. Was it using a different wheel than came with the block or does something slip over time. I mean more than musckles and skin.

Right you are, Sir! But then, Mama always said you wuz the smart one in the family...

I did some things last night and today during lunch. First off, I rolled the motor around again and got the same "stop points" as last time. Verified... I put the timing tape on it based on the marks and the new "TDC" point.

Earl brought home my re-jetted carb with the new power valve and various other stuff cleaned up and shiny. I bolted it on the engine last night, checked for gas leaks and found none. So, "being charitable and cautious" (Jimmy Buffett lyric) I started it up. I had to rotate the distributor a bit, but after a couple of tweaks, IT LIT OFF!!! Praise Jay-Suss!!! Idled a bit fast, so I tweaked the idle screw on the carb. Threw the timing light on it, got about 20, so I backed it down to 12. (Spec according to Earl is "10 to 15" at idle.)

Since the water pump wasn't turning and the fan was off the car, I only let it run for a few seconds. (Had the timing light hooked up and ready... Thinking positive!)

Today, I re-installed belts and pulleys and fan and topped up the radiator. Attempted to start it and it wouldn't crank. Then, it dawned on me... It ain't fuel injected now, it has a ol' fashunned carburetor installed. I pumped the accelerator three times, hit the starter and off it went. Still on time and idling about 800 RPM. I let it run for a while... Checking for leaks... None. Checking oil pressure, 50 psi on a warm idle. Coolant never got above 180...

Don't tell nobody, but I think it might be fixed.

Peace, Love and "Fingers Crossed"-
JDK

Honest answer: #DamnedIfIKnow...

I suspect it's several things, which may include the outer rim slipping on the inner. It also wouldn't surprise me if in all the rebuilding and swapping if I didn't get the "wrong" pointer paired up with the crank that was in the block. All of that probably got even more screwed up when I added the aftermarket crank and then aftermarket balancer.

I guess... Maybe... Possibly... :roll:

Ahh that brings back fond memories of something the young guys will have to google - it's called a slide rule

Glad to hear you got it figured out JD, I never had any doubt :cheers: :cheers:
