"Hello,
Question for those

"Hello,
Question for those with the magic books, I have what I think is a 5.7L. The serial on the back by the starter is 6825279, and the Rochester 4bbl carb has part # 17080563. From what I can find, it looks like a 85-86 engine, but the carb is a 1980 for a 7.4L/454Magnum???

Thanks!
Chris."

Can anyone tell me more about the engine serial number? The boat is an 89, but the engine was replaced by the previous owner, (no paperwork now), so I am *pretty* sure it is still a 5.7L, but maybe a previous year? Anything else I need to check?

[just asking to make future trips to the parts store more productive...] And I have a strange high-rpm loss of power when warm... for a future post when I have more details. Chasing carb/choke possibilities now. The archives here have been VERY helpful!!!!!

Thanks again,
Chris"
