When I was young I had a .090 over bored 283 with the 302ci solid lifter cam.
The motor was way faster than it sound have been as it had the small valve heads on it.
If it would have gone to the full .125 it would have been a 301!
Those days are gone.
Max overbore of my early LS1 is .005. LOL
Cheers.
