It was the crank gear that wouldn't even begin to go over the snout of the crank......looked like it was not machined thru and thru, there was a "lip" on the inner part of the gear......started with a small file working the lip out of it and then finished up with an old time wheel cylinder hone....
BTW: the factory Ford gear slipped right on with no problems, so I know it wasn't the crank...
BTW 2: when I put both gear sets side by side,Ray Charles could have seen the difference....when I took the Ford motor apart, I checked and the timing chain did have a very small amount of slack in the chain,I even considered re-using it,but being I'll have this engine in this car for years to come and hopefully thousands of miles,I decided in the grand scheme,the price of a new timing gear set was very small in the overall cost of the engine,that's why I ordered a new one from Comp Cams......Had this been a "strandard" overhaul of a stock engine, I would have re-used the timing set without hesitation....
Comparing the 2 side by side, the teeth on the Ford gear set are more "robust" and were better machined,showed very little to no wear on the gears/teeth.....whereas the Comp gear teeth are thinner and the teeth are almost pointed, actually looked like a timing gear set with 100,000 miles on it...
Kinda the same deal with the MSD/Duraspark distributors......I have a MSD distributor in my race car and one in the old engine of my street car,at least once a year I have to take them apart and clean out the rust and corrosion,easy to tell when it's time, as I rev the engine advance works fine, let off the gas and it takes forever to return if it does.....corrosion makes the centrifical advance stick all the time...
Now take the Ford Duraspark distributor,put in millions and millions of cars,ran for a gazillions of miles with no problems,NO corrosion!!!!!!!!! Why can't MSD and others make one that is as durable and dependable as the Ford unit?????
Especially when I can buy a reman Ford Duraspark distributor with lifetime warranty for under a 100 bucks....the one I'm using on this engine is for the older carbed models,non computer controlled with vacum advance, it retails for under 60 bucks as compared to $279.00 for a MSD unit that I know I'll have to work on at least once a year.......
