Question: 502 BBC Specs

[fine69]

Hi Folks,

Does anyone know of a resource where I can get engine specs for a 502 BBC?

I am trying to determine if a 454 can be modified to 502 by increasing the bore from 4.25 in. to 4.447 in. I believe the stroke is 4.00 in. for both.

Any help is appreciated.

Thanks.

I always learn something in here. Thanks Andre.... So, with 454 question. Is that a relatively straight-froward conversion?
