It is your car after all. On this site we are rabid fans of the Y-Block and believe strongly that they were given a bum rap by the scrub mania of the 50's and 60's. If you search this forum you will find a much different picture of the racing venues of that period and the Y-Block dominance. Yes thats correct Y-Block dominance.
Most of us are a bit older and have been fans of the Y for many years. We were first hand experiencing the slanted press that continues to this day. Almost any open brand site you visit is overrun with gm with the occasional token Ford/Mercury.
For these reasons we hate to see a Y-Block replaced with any other engine but especially by scrub's.
If the only reason you were considering the swap is to get a more modern engine I would recommend you give the rebuilt Y a shot first. With minimal expense to update the engine it can be a good performer along with the correctness of keeping the car "stock".
Again it is your car we can only recommend based on our personal experience and preferences. Thanks for coming to the forum to ask your questions. Chuck
