350

i have a 350 chevy in my 63 impala, i was just wondring which car that engine originally came from?...

Uhhh... there is almost no way to tell. The 350 was used in every single chevy RWD vehicle from 1970 to the late 80s, and is still used today in commercial trucks. It could have come from darn near anywhere.

Find some casting numbers, stamped numbers, and other identifications and get back to us. We can at least narrow it down.
