The engine appears to be a1964 truck engine based on the numbers. I’m trying to find out if this engine originally had an alternator or a generator. Any ideas of where to look are appreciated.
Thanks,

Those things are a royal pain in the butt to work with. Unless you're building something that's supposed to look factory original, a 10-SI internal regulated alternator from the middle 1970's or newer would be a much better choice, reliability-wise.

I’m trying to stay period correct, but it will be a driver and get used as originally intended so I’m okay with upgrades. | | | | | Joined: Mar 2010 Posts: 10,272 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,272 | I hope that you are planning staying out of the gas pedal. 327s are short stroke engines and rev up real fast. You have 4 u-joints and a transfer case designed to handle a low RPM 125 HP inline six 235.
I am not trying to dissuade you from doing your swap, I just know a guy with a '57 NAPCO who went with a 300 hp 350 crate motor and could not keep the bearings in the transfer case or was blowing out U-joints.
Granted, he could not keep his foot out of the gas.

There was a guy many years ago in our area who put a 389 in his GMC version of a Cameo that was also a NAPCO conversion. He was known for destroying the spider gears in his rear differentials by doing burnouts. I had a 1958 GMC factory NAPCO Carryall that had a 389 installed after the 336 wore out. I never had any problems other than keeping the fuel tank full. This is a truck version of the 327, 2 bolt mains, focus on low rpm torque etc. I’m 71 years old so I probably won’t get too crazy with the skinny pedal. Again, I do appreciate you advice.
Thanks,
