1100399 Open face diamond back Delco alternator

[McCune]

This is a 1100399 Rare internal regulated 10SI alternator with 6 spoke open face and diamond back regulator heatsink. Date is 9G25. Not sure what this number fits but it is so close to a Olds W30 alternator. This was a original core never taken apart until I got it. Retains all original parts except bearings and brushes. Bench tested and work perfect. Nice unit. Asking 800.00

Your”399” is really a “899”
Which is 1970 Corvette 350,300-350HP
And 454 /390 low horse
Definitely a good piece
Nice resto !
