Can someone help me nail down what this engine is or point me to the info?
I think it may be '60 thunderbird?

I guess I should have taken a pic of the s/n. It decodes to a 1960 T120 Bonneville but it has what I think is the wrong crank and an iron head, that's what made me think it is something else with T120 stampings or cases?

Thanks for the help guys.
I think I'll throw it back together like it was, should be good enough for a beater.....
Any idea what length pushrods should be in an iron head 650? Best I can tell they should be about 6 1/2" ish
