A 302 or 302 stroker can be built to mimic a 289 in appearance. unless you look at casting numbers and some other small items 98% of people would not know the difference.
You can even install the front timing cover with the
oil fill tube like early 289s had.
A mild 302 can give you more power and less stress than a 289. That said there is small difference in sound when you go up in displacement.
Do a little googling and don't forget some of
the advertisers here, they can provide a nice 289 or 302 that is
well built and they will stand behind it.
