To all knowing...
We have installed our 1960 generator on our dated 1957 engine. The engine has a single pully design and is not lining up with the generator. Did the 1960 engine have a two pulley's? Also, does the generator mounting braket have offset mounting holes or are they supposed to be in verticle alignment? the way it's looking right now, we'll have to machine a new mounting bracket...any thoughts? Again, your suggestions are welcome.
Respectfully,
Tom Spurgeon

P.S. The distance we're off is approximately the distance seen in the second photo where the temporary mounting is showing some threads.

Um... I'm speaking without thinking really here... but are you sure the bracket mounted to the manifold is the right way around? Imagine it with the bolts in the second bracket being behind the first, not in front. This would pull the generator back over an inch, and put the mounting tag at the front behind the curved adjuster.
If yu can't rotate the bracket, might this be a bracket set that would put the generator on the other side of the engine?
Just random ideas, tossed out for musing over.

[[EDIT: I've just photoshopped my first idea - the manifold bracket being flipped over. It would put the pulley almost exactly where the front silver generator ears casting currently is, which to me looks about right. PM me and I'll send you the pic via e-mail. ]]

Thanks for the responses so far. . .yes, Mark, I rotated the mounting bracket and it did put the the generator adjustment bar in front of the generator. It also put the pulley approximately 3/8" out-of-alignment toward the firewall's direction. Either way it wasn't lining up. That's why I was wondering if the '57 had a different mounting bracket. I see by the illustrations provided that there were at least two mounting brackets during the 59-62 years...was there another in '57? THANKS for the ideas!

Yes, there was an earlier, sort of double "L" shaped bracket. Not deep enough to be called a "U". Sorry, I don't have the measurements. They should be in Noland's book or any number of vendor catalogs.
I'm not clear here.
Are you mounting this on a 57 or a 60 Vette?
If your mounting it on a 57, the generator goes on the LEFT side
The car is a 1960, the engine is correct for a '57. After breaking the engine down, we found everything inside was new and calibrated at original spec's when we got the car...we didn't want to go through the hassle of finding the correct engine when this one was in perfect shape. So, we're trying to assemble '60 parts to a '57 engine. I'm sure that isn't helping matters. The generator mounting brackets bolt up fine...the issue is alignment. Since we believe the '57 engine has a single pulley design, we're trying to align the '60 generator -without too much Bubba looking work done here (kinda' like being a little pregnant). As it's looking now, we're looking into machining a mounting bracket with the mounting holes shifted 'a-bit'. Unless someone can offer a better idea (without replacing the new engine). Thanks again for the ideas. What we can't seem to find is information on the '57 generator mounting configuration. Did it have two mounting brackets? If so, was one of the brackets in vertical alignment? Thanks to K2, we saw two illustrations for 58-62 mounting designs. How different was the '57?

If the alignment problem is that the generator seems too far forward, about 5/8 inch, the problem is you have the wrong pulleys on the water pump and crank. If you had 2 groove pulleys ( which would be wrong ) the gen belt would be on the most forward grooves.

There are a few brackets for C1 generators. You may want to contact a parts vendor who could give you specific details on which one you need. Just make sure you have all the info on what pulleys, water pumps, balancer are on the motor you are trying to get the generator on. Is everything on the '57 motor stock?
Since you are not interested in authenticity,the easiest solution is to simply mill the round holes to slotted holes, thereby allowing you to adjust the generator to where you need it to be. Or make a new plate with the holes offset the amount of your misalignment.
Just a note to everyone who offered their advise. We notice in the back of our AIM that the fuel-injected model (which this is not) did not use the generator mounting plate with the u-bracket. The u-bracket mounted directly to the manifold. So, we took the mounting plate off and tried mounting the generator straight to the manifold via the u-bracket. WE HAVE ALIGNMENT!!!The only thing we may be concerned with down the road is how much heat transfer we're faced with possibly affecting the generator??? As far as the 'correctness' of the method, we should have used the correct engine...thanks again.
