it came out of a 65 tbird i had and the guy who had it before me is dead so as to what it came out of originally is unknown i was doubting if it even was a 410 but the guys son in law saw it out one day and my dad talked with him and said he helped build it and yes it was a 410
I don't want to knock your thread but I don't think they made a 410 w/2 barrel...they may have switched the original intake when it was rebuilt. I have owned 2 410 Mercs...(410 was the base Marauder motor in 1966, 428 was the Super Marauder) all info I have (original shop manual and Detriot Iron Manaul on CD) only lists the 410 w/4 barrel intake. Again not to say someone couldn't have switched it out at some point.
If it is a 410 it will have a 428 crank in it...well worth your asking price all by it self.
