I did a 87 GN with 15k on it at the time(1989) with a 502... Now I believe he has a 560 Shafferoff motor in there . NICE car to . Haven't scene him for a few years . Not a big deal to do
I think you should pay someone to do it right . You can make such a mess and you can spend a lot of time an aggravation tryin to save a few bucks :rolleyes:
