Hello everyone hope you are doing well, and thanks for taking the time to read my question. I have a 84 12a that I am looking to do the RB intake and holley carb swap on. I recently found a RB intake and Holley 600 for $300 and would like to pick it up. My 12a is bone stock, so I've always been told the 600 is to big for a stock engine. So I was curious if it would be possible for me to rebuild the 600 with a 465 kit.
