The way I hear it is the last year Studebaker made cars in the US is 64. They closed in the states and continued in Canada. My 65 was made in Canada and since they no longer made their own V8 they bought the Chevy 283 which was made in the St. Catherines plant (known as McKinnen Industries at the time). I've asked the Studebaker guys and they say it is a chevy small block and the transmission will match.
