Does anybody have any info on how to tune up a 410 or 428 for maximum horsepower?
I recently gained control of a 410 that came out of a 66 or 67 Mercury. I would like to bore it into a 428 and get the maximum horsepower. I saw a post on here from a DennyW that said he has a 428 that puts out 575 HP. Any info on that would be greatly appreciated. Thanks
