I want to change the cast iron 454 exhaust to 496 exhaust. Any advice from those who may have done this already? Will there be issues with the throttle bracket and electronic bracket? Thanks for any help.

My boat came with a 454 carb motor and the 496 exhaust. I do not seem to have any issues with any of the brackets that bolt to the 496 exhaust. If anything you may need to either modify or fabricate brackets.
